This is Gonna Hurt: The Documentaries is a six part series based on the photo book and album by the same name. There are interviews with Nikki Sixx which explain the entire photo/music concept as well. It is interesting that Nikki and SIXX: AM are really making their new projects so multi-dimensional.
The first two parts are on HULU now. Check it out.
(part two is for mature audiences. You've been warned).
