Blood into wine (2010)

Music fans know Maynard James Keenan as the frontman of such bands as Tool, A Perfect Circle, and Puscifer, but in this documentary filmmakers Christopher Pomerenke and Ryan Page offer a closer look at one of the prolific rocker's more unexpected hobbies -- winemaking. Along with his business partner Eric Glomski, Keenan has managed to transform an arid stretch of Arizona desert into a lush vineyard that yields some particularly tasty grapes. Through unguarded conversations with Keenan and Glomski, Pomerenke and Page discover just what got the pair interested in winemaking, and why they chose such a hostile natural environment to serve as the site of their winery.
