Holly had been making demo recordings with local musician friends since 1954. Sonny Curtis, Jerry Allison, and Larry Welborn participated in these sessions. In 1956 Holly's band, then known informally as Buddy and the Two Tones (Holly with Sonny Curtis and Don Guess; posthumous releases refer to the Three Tunes), recorded an album's worth of rockabilly numbers in Nashville, Tennessee, for Decca. The records were not more than mildly successful, and the band did not achieve financial success until 1957, when the producer and recording engineer Norman Petty recorded Holly's sessions in Clovis, New Mexico.
