Musical help required

The only problem with writing That Book About Rock that I've been thinking about for ages, is that I don't really know that much about rock. I mean, I like it. I listen to it. But I'm not nerdily proficient in its trivia and anecdotes. Luckily I live with someone who is, but I want more! At the moment I'm reading The Penguin Book of Rock & Roll Writing, and Rock Chicks: the Hottest Female Rockers from the 1960s to Now. What musical books/films/documentaries do you recommend? Fiction and non-fiction. I just need to get into the mood of it all.
