Dear Zachary was awesome... Thanks for the recommend...
My favorite music documentary is probably Hype!
http://www.imdb.com/title/tt0116589/ about the Seattle music scene in the late 80s early 90s
I've seen so many docs I can't remember them all haha, watched Dark Days the other day, it was pretty decent...
http://www.imdb.com/title/tt0235327/ about the homeless in NYC that live in the subway.
Also recommend "The War Photographer"
