After a recording session, Bing Crosby suggested that Paul build a recording studio so he could produce the sound he wanted. Paul started his studio in the garage of his home on North Curson Street in Hollywood. The studio drew many vocalists and musicians who wanted the benefit of his expertise. His experiments included microphone placement, track speed, and recording overdubs. These methods resulted in a clarity previously unheard in this type of multitrack recording. People started to consider his recording techniques as instruments—as important to production as a guitar, bass, or drums.
