"Miller established the primacy of the producer, proving that even more than the artist, the accompaniment, or the material, it was the responsibility of the man in the recording booth whether a record flew or flopped. Miller also conceived the idea of the pop record 'sound' per se: not so much an arrangement or a tune, but an aural texture (usually replete with extramusical gimmicks) that could be created in the studio and then replicated in live performance, instead of the other way around. Miller was hardly a rock 'n' roller, yet without these ideas there could never have been rock 'n' roll. 'Mule Train', Miller's first major hit (for Frankie Laine) and the foundation of his career, set the pattern for virtually the entire first decade of rock. The similarities between it and, say, 'Leader of the Pack', need hardly be outlined here."
