”;Blood Into Wine”;

Screens 6 p.m. April 22 at the HIFF 2010 Spring Showcase in the Regal Dole Cannery Stadium 18

Much like Maynard James Keenan, “;Blood Into Wine”; is a decidedly unorthodox and sometimes irreverent account of the rock musician's life in vino.

Keenan said he got filmmakers Ryan Page and Christopher Pomerenke to do a re-edit after an initial film festival screening because “;it was too much of a biography in the first version and not enough about wine making.”;

“;Blood Into Wine,”; however, is still very much about him — and there are segments that feature his music — but now his mentor and business partner, Eric Glomski, has a fair amount of face time to fill in about the business and his own life philosophy, all told with enthusiasm.

Keenan realizes that some of his uninformed fans will never understand how he could immerse himself in this particular business and lifestyle, so he chides them by adding comedic segments with his savvy friends Eric Wareheim and Tim Heidecker (in a hilariously excoriating extended bit), and Patton Oswalt and Bob Odenkirk.

But you also see Keenan at his most candid and unguarded, particularly when he speaks about his late mother and the current state of his music, which has taken him away from the initial “;Sturm und Drang”; of Tool. It was those songs and tortured-but-focused artistry that made him popular — but because he's worked out the issues that fueled so much of what he contributed to Tool, “;I don't want to scream my whole life.”;

He's instead found his muse in the wine grape. A detour into the snooty, rarefied world of wine criticism and cultivated palates returns to Keenan and Glomski when friend and European wine critic James Suckling gives approving remarks that basically validate Keenan's Arizona-grown wines.

It's all a bit loaded in Keenan's favor, but if you're already a fan of his, you'll enjoy this film and even learn a bit more about the arduous task of making wine.
