Maynard James Keenan, the evil genius behind Tool, A Perfect Circle, and Puscifer, is also seriously passionate about winemaking. He's got a vineyard in Arizona, and it's the subject of an upcoming documentary called Blood Into Wine, made by the guys who made the Moog doc. Below you'll find the trailer, and here you'll find our interview with Keenan, which touches quite a bit on his love of vino.
