At thirteen, Norman began cutting records in his father's filling station. With money earned from the Norman Petty Trio's "Mood Indigo," Petty converted a family grocery store next door into a modern recording studio where he experimented with echo and microphone settings. In 1957, Petty made rock 'n' roll history by recording Buddy Holly and the Crickets' "That'll Be the Day." The sound influenced a generation, and his techniques are still used today.
