2010 three CD collection devoted to "The Pure Essence Of West Coast Rock 'n' Roll". Los Angeles may well be synonymous with movie stars, the Capitol Tower and Sunset Boulevard, but it also ranks as a leading location on the road to Rock 'n' Roll. The music's emergence in the 1950s brought about a profusion of area recording facilities, many of which were dotted around the city's 498 square miles. These included Radio Recorders, United, Gold Star and Master Recorders, and the studio owners were quick to learn that it paid to be as diverse as possible. The day might start with a film dubbing, ahead of a television commercial being taped over the lunch hour. Then in the afternoon the microphones could be adjusted to record a big band, followed by a teenage pop session in the evening. These very same studios recorded some of the finest Rock to emerge from the U.S. during the heady days of early R 'n' R!  75 tracks. Fantastic Voyage.
