Popular music of the 1960s was dominated by young bands like the Beach Boys, the Mamas & the Papas, Jan and Dean, and the Monkees. Listening to rock and roll on jukeboxes and car radios created devoted fans of these groups, whose music communicated the optimism and sorrow of a generation contending with strong countercultural forces. Record companies happily supplied the public with new songs and musical groups, all packaged with artistic photographs and biographical profiles. Left out of the story was an important historical fact: the bands, in some, but not all, cases, did not play the instruments heard on their records. Instead, the task of recording the perfect tempo, pitch, and timbre fell to a small group of accomplished session musicians. The Wrecking Crew documents the work of studio players who recorded the tracks for such hits as "California Dreamin'", "These Boots Are Made for Walkin'", "Be My Baby", "The Beat Goes On", and "Good Vibrations". Interviews with producers, engineers, and session musicians reveal the warmth and humor that allowed their collective talents to turn a simple chord chart into an international phenomenon.
