Harrison, only 17 years old in August 1960, obtained permission to stay in Hamburg by lying to the German authorities about his age. Initially placing the group at the Indra Club, Koschmider moved them to the Kaiserkeller in October after the Indra was closed down due to noise complaints. When they violated their contract by performing at The Top Ten Club, a rival venue, Koschmider reported the underage Harrison to the authorities, leading to his deportation in November. A week later, McCartney and Best were arrested for arson after they set fire to a condom nailed to a wall in their room; they were also deported. Lennon returned to Liverpool in mid-December, while Sutcliffe remained in Hamburg with his new German fiancée, Astrid Kirchherr, for another month. Kirchherr took the first professional photos of the group and cut Sutcliffe's hair in the German "exi" (existentialist) style of the time, a look later adopted by the other Beatles.During the next two years, the group were resident for further periods in Hamburg. They used Preludin both recreationally and to maintain their energy through all-night performances. When Sutcliffe decided to leave the band in early 1961 and resume his art studies in Germany, McCartney took up the bass. German producer Bert Kaempfert contracted what was now a four-piece to act as Tony Sheridan's backing band on a series of recordings. Credited to "Tony Sheridan & The Beat Brothers", the single "My Bonnie", recorded in June and released four months later, reached number 32 on the Musikmarkt chart. The Beatles were also becoming more popular back home in Liverpool. During one of the band's frequent appearances there at the Cavern Club, they encountered Brian Epstein, a local record store owner and music columnist. When the band appointed Epstein manager in January 1962, Kaempfert agreed to release them from the German record contract. After Decca Records rejected the band with the comment "Guitar groups are on the way out, Mr. Epstein", George Martin signed the group to EMI's Parlophone label. News of a tragedy greeted them on their return to Hamburg in April. Meeting them at the airport, a stricken Kirchherr told them of Sutcliffe's death from a brain hemorrhage.Bruno had the idea of bringing in rock groups to play in various clubs. They had this formula. It was a huge nonstop show, hour after hour, with a lot of people lurching in and the other lot lurching out. And the bands would play all the time to catch the passing traffic. In an American red-light district, they would call it nonstop striptease.Many of the bands that played in Hamburg were from Liverpool. ... It was an accident. Bruno went to London to look for bands. But he happened to meet a Liverpool entrepreneur in Soho, who was down in London by pure chance. And he arranged to send some bands over.
General critical opinion eventually turned in favour of the White Album, and in 2003 Rolling Stone ranked it as the tenth greatest album of all time. Pitchfork describes it as "large and sprawling, overflowing with ideas but also with indulgences, and filled with a hugely variable array of material ... its failings are as essential to its character as its triumphs." Allmusic observes, "The Beatles' two main songwriting forces were no longer on the same page, but neither were George and Ringo"; yet "Lennon turns in two of his best ballads", McCartney's songs are "stunning", Harrison is seen to have become "a songwriter who deserved wider exposure" and Starr's composition is "a delight". By now the interest in their lyrics was taking a serious turn. When Lennon's song "Revolution" had been released as a single in August ahead of the White Album, its messages seemed clear: "free your mind", and "count me out" of any talk about destruction as a means to an end. In a year characterized by student protests that stretched from Warsaw to Paris to Chicago, the response from the radical left was scathing. However, the White Album version of the song, "Revolution 1", added an extra word, "count me out ... in", implying a change of heart since the single's release. The chronology was in fact reversed—the ambivalent album version was recorded first—but some felt that Lennon was now saying that political violence might indeed be justifiable. The Yellow Submarine LP finally appeared in January 1969. It contained only four previously unreleased songs, along with the title track (already issued onRevolver), "All You Need Is Love" (already issued as a single and on the US Magical Mystery Tour LP) and seven instrumental pieces composed by Martin. Because of the paucity of new Beatles music, Allmusic suggests the album might be "inessential" but for Harrison's "It's All Too Much", "the jewel of the new songs ... resplendent in swirling Mellotron, larger-than-life percussion, and tidal waves of feedback guitar ... a virtuoso excursion into otherwise hazy psychedelia".The critical response ... ranged from mixed to flat. In marked contrast to Sgt. Pepper, which had helped to establish an entire genre of literate rock criticism, the White Album inspired no critical writing of any note. Even the most sympathetic reviewers ... clearly didn't know what to make of this shapeless outpouring of songs. Newsweek's Hubert Saal, citing the high proportion of parodies, accused the group of getting their tongues caught in their cheeks.
In The Beatles as Musicians, Walter Everett points out 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, comparing the two composers in Revolution in the Head, describes McCartney as "a natural melodist—a creator of tunes capable of existing apart from their harmony". His melody lines are characterized 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. ... His faintly behind-the-beat style subtly propelled The Beatles, his tunings brought the bottom end into recorded drum sound, and his distinctly eccentric fills remain among the most memorable in pop music."In their initial incarnation as cheerful, wisecracking moptops, the Fab Four revolutionized 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.
Harrison echoed Martin's description of his stabilizing role: "I think we just grew through those years together, him as the straight man and us as the loonies; but he was always there for us to interpret our madness—we used to be slightly avant-garde on certain days of the week, and he would be there as the anchor person, to communicate that through the engineers and on to the tape."Compared with Paul's songs, all of which seemed to keep in some sort of touch with reality, John's had a psychedelic, almost mystical quality. ... John's imagery is one of the best things about his work—"tangerine trees", "marmalade skies", "cellophane flowers." ... I always saw him as an aural Salvador Dalí, rather than some drug-ridden record artist. On the other hand, I would be stupid to pretend that drugs didn't figure quite heavily in The Beatles' lives at that time. At the same time they knew that I, in my schoolmasterly role, didn't approve. ... Not only was I not into it myself, I couldn't see the need for it; and there's no doubt that, if I too had been on dope, Pepper would never have been the album it was.
