ROCK

Rock music is a genre of popular music that entered the mainstream in the 1950s. It has its roots in 1940s and 1950s rock and roll, rhythm and blues, country music and also drew on folk music, jazz and classical music. The sound of rock often revolves around the electric guitar, a back beat laid down by a rhythm section of electric bass guitar, drums, and keyboard instruments such as Hammond organ, piano, or, since the 1970s, synthesizers. Along with the guitar or keyboards, saxophone and blues-style harmonica are sometimes used as soloing instruments. In its "purest form", it "has three chords, a strong, insistent back beat, and a catchy melody."[1]

In the late 1960s and early 1970s, rock music developed different subgenres. When it was blended with folk music it created folk rock, with blues to create blues-rock and with jazz, to create jazz-rock fusion. In the 1970s, rock incorporated influences from soul, funk, and Latin music. Also in the 1970s, rock developed a number of subgenres, such as soft rock, glam rock, heavy metal, hard rock, progressive rock, and punk rock. Rock subgenres that emerged in the 1980s included new wave, hardcore punk and alternative rock. In the 1990s, rock subgenres included grunge, Britpop, indie rock, and nu metal.

A group of musicians specializing in rock music is called a rock band or rock group. Many rock groups consist of an electric guitarist, lead singer, bass guitarist, and a drummer, forming a quartet. Some groups omit one or more of these roles or utilize a lead singer who plays an instrument while singing, sometimes forming a trio or duo; others include additional musicians such as one or two rhythm guitarists or a keyboardist. Rock bands from some genres, particularly those related to rock's foundations in rock and roll, include a saxophone. More rarely, groups also utilize bowed stringed instruments such as violins or cellos, and brass instruments such as trumpets or trombones.

More recently the term rock has been used as a blanket term including forms such as pop music, reggae music, soul music, and sometimes even hip hop, with which it has often been contrasted through much of its history.


Rock and roll



The foundations of rock music are in rock and roll, which originated in the United States during the late 1940s and early 1950s, and quickly spread to much of the rest of the world. Its immediate origins lay in a mixing together of various popular musical genres of the time, including rhythm and blues, gospel music, and country and western. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music for a multi-racial audience, and is credited with first using the phrase "rock and roll" to describe the music.

There is much debate as to what should be considered the first rock and roll record. One leading contender is "Rocket 88" by Jackie Brenston and his Delta Cats (in fact, Ike Turner and his band The Kings of Rhythm), recorded by Sam Phillips for Sun Records in 1951. Four years later, Bill Haley's "Rock Around the Clock" (1955) became the first rock and roll song to top Billboard magazine's main sales and airplay charts, and opened the door worldwide for this new wave of popular culture.

Rolling Stone magazine argued in 2004 that "That's All Right (Mama)" (1954), Elvis Presley's first single for Sun Records in Memphis, was the first rock and roll record., but, at the same time, Big Joe Turner's "Shake, Rattle & Roll", later covered by Haley, was already at the top of the Billboard R&B charts. Other artists with early rock and roll hits included Chuck Berry, Bo Diddley, Fats Domino, Little Richard, Jerry Lee Lewis, and Gene Vincent. Soon rock and roll was the major force in American record sales and crooners, such as Eddie Fisher, Perry Como, and Patti Page, who had dominated the previous decade of popular music, found their access to the pop charts significantly curtailed.

Rock and roll has been seen as leading to a number of distinct sub-genres, including rockabilly, combining rock and roll with "hillbilly" country music, which was usually played and recorded in the mid-1950s by white singers such as Carl Perkins, Jerry Lee Lewis, Buddy Holly and with the greatest commercial success, Elvis Presley. In contrast doo wop placed an emphasis on multi-part vocal harmonies and meaningless backing lyrics (from which the genre later gained its name), which were usually supported with light instrumentation and had its origins in 1930s and 40s African American vocal groups. Acts like The Crows, The Penguins, The El Dorados and The Turbans all scored major hits, and groups like The Platters, with songs including "The Great Pretender" (1955), and The Coasters with humorous songs like "Yakety Yak" (1958), ranked among the most successful rock and roll acts of the period. The era also saw the growth in popularity of the electric guitar, and the development of a specifically rock and roll style of playing through such exponents as Chuck Berry, Link Wray, and Scotty Moore.

In the United Kingdom, the trad jazz and folk movements brought visiting blues music artists to Britain. Lonnie Donegan's 1955 hit "Rock Island Line" was a major influence and helped to develop the trend of skiffle music groups throughout the country, many of which, including John Lennon's The Quarrymen, moved on to play rock and roll.

Commentators have traditionally perceived a decline of rock and roll in the late 1950s and early 1960s. By 1959, the death of Buddy Holly, The Big Bopper and Richie Valens in a plane crash, the departure of Elvis for the army, the retirement of Little Richard to become a preacher, prosecutions of Jerry Lee Lewis and Chuck Berry and the breaking of the payola scandal (which implicated major figures, including Alan Freed, in bribery and corruption in promoting individual acts or songs), gave a sense that the initial rock and roll era had come to an end.

Psychedelic rock



Psychedelic music's LSD-inspired vibe began in the folk scene, with the New York-based Holy Modal Rounders using the term in their 1964 recording of "Hesitation Blues". The first group to advertise themselves as psychedelic rock were the 13th Floor Elevators from Texas, at the end of 1965; producing an album that made their direction clear, with The Psychedelic Sounds of the 13th Floor Elevators the following year. The Beatles introduced many of the major elements of the psychedelic sound to audiences in this period, with "I Feel Fine" using guitar feedback; in late 1965 the Rubber Soul album included the use of a sitar on "Norwegian Wood" and they employed backmasking on their 1966 single B-side "Rain" and other tracks that appeared on their Revolver album later that year.

Psychedelic rock particularly took off in California's emerging music scene as groups followed the Byrds from folk to folk rock from 1965. The psychedelic life style had already developed in San Francisco and particularly prominent products of the scene were The Grateful Dead, Country Joe and the Fish, The Great Society and Jefferson Airplane. The Byrds rapidly progressed from purely folk rock in 1966 with their single "Eight Miles High", widely taken to be a reference to drug use. In Britain arguably the most influential band in the genre were The Yardbirds, who, with Jeff Beck as their guitarist, increasingly moved into psychedelic territory, adding up-tempo improvised "rave ups", Gregorian chant and world music influences to songs including "Still I'm Sad" (1965) and "Over Under Sideways Down" (1966). From 1966 the UK underground scene based in North London, supported new acts including Pink Floyd, Traffic and Soft Machine. The same year saw Donovan's folk-influenced hit album Sunshine Superman, considered one of the first psychedelic pop records, as well as the débuts of blues rock bands Cream and The Jimi Hendrix Experience, whose extended guitar-heavy jams became a key feature of psychedelia.

Psychedelic rock reached its apogee in the last years of the decade. 1967 saw the Beatles release their definitive psychedelic statement in Sgt. Pepper's Lonely Hearts Club Band, including the controversial track "Lucy in the Sky with Diamonds" and the Rolling Stones responded later that year with Their Satanic Majesties Request. Pink Floyd produced what is usually seen as their best psychedelic work The Piper at the Gates of Dawn. In America the Summer of Love was prefaced by the Human Be-In event and reached its peak at the Monterey Pop Festival, the later helping to make major American stars of Jimi Hendrix and The Who, whose single "I Can See for Miles" delved into psychedelic territory. Key recordings included Jefferson Airplane's Surrealistic Pillow and The Doors' Strange Days. These trends climaxed in the 1969 Woodstock festival, which saw performances by most of the major psychedelic acts, but by the end of the decade psychedelic rock was in retreat. Brian Jones of the Rolling Stones and Syd Barrett of Pink Floyd were early casualties, the Jimi Hendrix Experience and Cream broke up before the end of the decade and many surviving acts, moved away from psychedelia into more back-to-basics "roots rock", the wider experimentation of progressive rock, or riff laden heavy rock.

Blues-Rock



Although the first impact of the British Invasion on American popular music was through beat and R&B based acts, the impetus was soon taken up by a second wave of bands that drew their inspiration more directly from American blues, including the Rolling Stones and the Yardbirds. British blues musicians of the late 1950s and early 60s had been inspired by the acoustic playing of figures such as Lead Belly, who was a major influence on the Skiffle craze, and Robert Johnson. Increasingly they adopted a loud amplified sound, often centred around the electric guitar, based on the Chicago blues, particularly after the tour of Britain by Muddy Waters in 1958, which prompted Cyril Davies and guitarist Alexis Korner to form the band Blues Incorporated. The band involved and inspired many of the figures of the subsequent British blues boom, including members of the Rolling Stones and Cream, combining blues standards and forms with rock instrumentation and emphasis.
The other key focus for British blues was around John Mayall who formed the Bluesbreakers, whose members included Eric Clapton (after his departure from The Yardbirds) and later Peter Green. Particularly significant was the release of Blues Breakers with Eric Clapton (Beano) album (1966), considered one of the seminal British blues recordings and the sound of which was much emulated in both Britain and the United States. Eric Clapton went on to form supergroups Cream, Blind Faith and Derek and the Dominos, followed by an extensive solo career that has been seminal in bringing blues-rock into the mainstream. Green, along with the Bluesbreaker's rhythm section Mick Fleetwood and John McVie, formed Peter Green's Fleetwood Mac, who enjoyed some of the greatest commercial success in the genre. In the late '60s Jeff Beck, also an alumnus of the Yardbirds, moved blues-rock in the direction of heavy rock with his band, The Jeff Beck Group. The last Yardbirds guitarist Jimmy Page went on to form The New Yardbirds which rapidly became Led Zeppelin, whose early work was largely based on adaptations of blues standards. Many of the song on their first three albums and occasionally later in their careers, were expansions on traditional blues songs.

In American blues-rock had been pioneered in the early 1960s by guitarist Lonnie Mack, but the genre began to take off in the mid-60s as acts followed developed a sound similar to British blues musicians. Key acts included Paul Butterfield (whose band acted like Mayall's Bluesbreakers in Britain as a starting point for many successful musicians), Canned Heat, the early Jefferson Airplane, Janis Joplin, Johnny Winter, The J. Geils Band and Jimi Hendrix with his power trios, The Jimi Hendrix Experience and Band of Gypsys, whose guitar virtuosity and showmanship would be among the most emulated of the decade. Blues-rock bands like Allman Brothers Band, Lynyrd Skynyrd and eventually ZZ Top from the southern states, incorporated country elements into their style to produce distinctive Southern rock.

Early blues-rock bands often emulated jazz, playing long, involved improvisations which would later be a major element of progressive rock. From about 1967 bands like Cream and The Jimi Hendrix Experience had begun to move away from purely blues-based music into psychedelia. By the 1970s blues-rock had become heavier and more riff-based, exemplified by the work of Led Zeppelin and Deep Purple, and the lines between blues-rock and hard rock "were barely visible", as bands began recording rock-style albums. The genre was continued in the 1970s by figures such as George Thorogood and Pat Travers, but, particularly on the British scene (except perhaps for the advent of groups such as Status Quo and Foghat who moved towards a form of high energy and repetitive boogie rock), bands became focused on heavy metal innovation, and blues-rock began to slip out of the mainstream.
