Re: What's your favorite music documentary?
I don't know if anybody has mentioned it yet but there's an awesome series titled "last 24" ...or is it "final 24"? Either way, it's class. It re-enacts the final 24 hours of celeb who have passed away in strange circumstances and they trace back through their lives to find how they got to that point.
They've done the likes of Janis Joplin, Sid Vicious, Jimi Hendrix, Jim Morrison etc. I really recommend checking them out, I'm not a massive fan of any of the people who were featured in the docs but they were still really interesting.
