Here's a fireball documentary about the 1970s, when filmmakers were stoked by sex, drugs, rock and, oh, yeah, social conscience. Directors Richard LaGravenese and the late Ted Demme interview the likes of Scorsese, Coppola and Altman and show great clips, from M*A*S*H to Apocalypse Now. As Paul Schrader, who wrote Taxi Driver, points out, "The film business was a decadent, decaying, emptied whorehouse, and it had to be assaulted." Still does.

“Help Me”

Joni Mitchell wrote and recorded this song for her album Court and Spark, but she had to switch from her regular band to make the song sound exactly the way she wanted. "I had attempted to play my music with rock & roll players," she told Rolling Stone. "They’d laugh, 'Awww, isn't that cute? She's trying to teach us how to play.'" Mitchell switched to a jazz band, Tom Scott’s L.A. Express, and scored the biggest hit of her career in the process.
