The highlights of Bowie, Iggy & Lou 1971 - 1973 might not seem rich enough, considering the short period of time. Much in the vein of a perfect storm, these years turned out to be a time when each artist needed a creative shock in order to keep moving. Bowie was on the rise, Reed had dropped out, and Iggy had burned out... The shift Bowie made from struggling musician to pop phenom had a dose of Warhol and what Velvet Underground brought to the U.K., but it wasn't until this time that Bowie and Reed met. The raw energy that Iggy Pop had displayed with The Stooges had a huge impact on breaking Reed and Bowie away from art-rock and pop. On reflection, you might say that this meeting of the minds was a bigger benefit for Bowie than the others, considering his success in growing and sustaining a career for decades after this point. The documentary doesn't make this suggestion, but it does suggest that none of the three would have achieved their later success without this chance encounter.
Arguably a niche production for a niche audience, Sacred Triangle: Bowie, Iggy & Lou 1971 - 1973 is a great addition for fans. It also may strike a nerve with some early Gen-Xers or late Boomers that spent their adolescence listening to this stuff. All three men have continued making significant music, influencing diverging streams of artists that may not realize how much they owe to the creative spark engendered in Bowie, Iggy & Lou during the early '70s.
