Sir George Martin, the so-called 5th Beatle, was the producer who translated four Liverpool lads into studio language. I first clocked him at Parlophone in the 1950s; from 1962-1970 he shaped The Beatles' records with tape loops, strings, and ruthless edits that made pop feel like cinema. Alongside them he guided fellow Merseybeat names like Gerry & the Pacemakers and Billy J. Kramer & the Dakotas (1963-1965), plus Cilla Black (1963-1966). After leaving EMI he built AIR and, in the 1970s, produced Paul McCartney & Wings (1973), America (1974-1976), and Jeff Beck (1975). He rarely shouted, but the speakers did. That is why they called him the 5th Beatle, and nobody argued.
