I got it on Netflix about a month and a half ago, because Blood is my favorite chili album. Suffice to say, I loved the documentary. The band members offer some very insightful perspectives of their surroundings and their music. You see them all record the B-Sides, including Sikamikanico, and record, track by track the album, as well as each member explaining their roles, and the stories behind some of the songs. Very good documentary, and shot in a very good, casual style.
I rented this DVD from the local video store expecting a concert of sorts but was suprised to find it was just the making of Blood Sugar Sex Magik. It was very insightful and interesting look at the recording process of one of the most infleuntial albums of all time.
