A couple more with links and blurbs:
Echo In The Canyon
Echo In The Canyon celebrates the explosion of popular music that came out of LA's Laurel Canyon in the mid-60s as folk went electric and The Byrds, The Beach Boys, Buffalo Springfield and The Mamas and the Papas gave birth to the California Sound.
20 Feet from Stardom
Filmmaker Morgan Neville shines a long-overdue spotlight on the hit-making contributions of longtime backup singers like Darlene Love and Merry Clayton.
Amy
As riveting as it is sad, Amy is a powerfully honest look at the twisted relationship between art and celebrity -- and the lethal spiral of addiction.
Watching Amy is really like watching a slow-motion train wreck. But she was so damn talented.
"Miles Davis The Birth of the Cool" was one of my favorites but A) you need to be a fan and B) it was on PBS and I don't know if it's just out there to watch yet.
