input: In Icons of Rock: An Encyclopedia of the Legends Who Changed Music Forever, Scott Schinder and Andy Schwartz describe the Beatles' musical evolution: In their initial incarnation as cheerful, wisecracking moptops, the Fab Four revolutionised the sound, style, and attitude of popular music and opened rock and roll's doors to a tidal wave of British rock acts. Their initial impact would have been enough to establish the Beatles as one of their era's most influential cultural forces, but they didn't stop there. Although their initial style was a highly original, irresistibly catchy synthesis of early American rock and roll and R&B, the Beatles spent the rest of the 1960s expanding rock's stylistic frontiers, consistently staking out new musical territory on each release. The band's increasingly sophisticated experimentation encompassed a variety of genres, including folk-rock, country, psychedelia, and baroque pop, without sacrificing the effortless mass appeal of their early work. In The Beatles as Musicians, Walter Everett describes Lennon and McCartney's contrasting motivations and approaches to composition: "McCartney may be said to have constantly developed - as a means to entertain - a focused musical talent with an ear for counterpoint and other aspects of craft in the demonstration of a universally agreed-upon common language that he did much to enrich. Conversely, Lennon's mature music is best appreciated as the daring product of a largely unconscious, searching but undisciplined artistic sensibility." Ian MacDonald describes McCartney as "a natural melodist - a creator of tunes capable of existing apart from their harmony". His melody lines are characterised as primarily "vertical", employing wide, consonant intervals which express his "extrovert energy and optimism". Conversely, Lennon's "sedentary, ironic personality" is reflected in a "horizontal" approach featuring minimal, dissonant intervals and repetitive melodies which rely on their harmonic accompaniment for interest: "Basically a realist, he instinctively kept his melodies close to the rhythms and cadences of speech, colouring his lyrics with bluesy tone and harmony rather than creating tunes that made striking shapes of their own." MacDonald praises Harrison's lead guitar work for the role his "characterful lines and textural colourings" play in supporting Lennon and McCartney's parts, and describes Starr as "the father of modern pop/rock drumming".

input: After Brian Jones was removed from The Rolling Stones in June 1969, John Mayall recommended Taylor to Mick Jagger. Taylor believed he was being called in to be a session musician at his first studio session with the Rolling Stones. An impressed Jagger and Keith Richards invited Taylor back the following day to continue rehearsing and recording with the band. He overdubbed guitar on "Country Honk" and "Live With Me" for the album Let It Bleed, and on the single "Honky Tonk Women" released in the UK on 4 July 1969. Taylor's onstage debut as a Rolling Stone, at the age of 20, was the free concert in Hyde Park, London on 5 July 1969. An estimated quarter of a million people attended for a show that turned into a tribute to Brian Jones, who had died two days before the concert. The Rolling Stones' 1971 release Sticky Fingers included "Sway" and "Moonlight Mile" which Taylor and Jagger had completed in Richards' absence. At the time Jagger stated: "We made [tracks] with just Mick Taylor, which are very good and everyone loves, where Keith wasn't there for whatever reasons ... It's me and [Mick Taylor] playing off each other - another feeling completely, because he's following my vocal lines and then extemporizing on them during the solos." However, Taylor was only credited as co-author of one track, "Ventilator Blues", from the album Exile on Main St. (1972). After the 1973 European tour, Richards's drug problems had worsened and began affecting the ability of the band to function as a whole. Between recording sessions, the band members were living in various countries and during this period Taylor appeared on Herbie Mann's London Underground (1974) and also appeared on Mann's album Reggae (1974).
