I've seen the fantastic documentary, The Wrecking Crew, about the legendary group of studio musicians who played the instruments on a great many of the songs recorded by famous groups of the 1960s and 1970s. The documentary is finished, but the filmmaker (son of Wrecking Crew guitarist Tommy Tedesco) needs $250k to pay the licensing fees for the 120+ music cues in the film. He's launched a Kickstarter to raise the funds and is well over halfway towards his funding goal. I'm rooting for this to happen because this film deserves to be seen.
This is a documentary film about an elite group of studio session musicians in Los Angeles in the 1960’s who played on hits for the Beach Boys, Frank Sinatra, Nancy Sinatra, Sonny and Cher, Jan & Dean, The Monkees, Gary Lewis and the Playboys, Mamas and Papas, 5th Dimension, Tijuana Brass, Ricky Nelson, Elvis Presley, Johnny Rivers and Phil Spector's Wall of Sound and that’s just a few! The amount of work in which they were involved was tremendous.
