Monterey Pop

This has to be one of the greatest concert documentaries ever made. You get to see some of the greatest early performances by some of rock's greatest legends (Jimi Hendrix, The Who and Janis Joplin) as well as the performance of one band on their last legs, the Mamas and the Papas. The festival also could be seen as a turning point in popular music due to the fact that after the festiveal the more singles oriented acts were being pushed aside in favor of the more progressive album oriented artists.

Also, if you need more convincing of how much of a pivotal event this was, check out the outtakes video. It contains many of the performances that didn't make it to the film, including Buffalo Springfield without Neil Young who had quit the band a month before their scheduled appearance. Replacing him for this performance was David Crosby, who performed earlier with the Byrds but joined his friend Stephen Stills and the rest of the Springfield for the show (less than a year later Crosby and Stills would team up with Graham Nash and the rest is history). Also check out Laura Nyro. Legend has it that she was booed off the stage. However, she gets a nice applause for her renditions of her classics "Wedding Bell Blues" and "Poverty Train".
