Maynard James Keenan, perhaps best known in some circles as the frontman for Tool, is headed to Milwaukee in June, but sorry prog rockers, it's not for a repeat of his 2007 Summerfest performance.

Keenan will be at Whole Foods Market from 4 to 7 p.m. on Wednesday, June 3 not as a rocker, but as a vintner. He and friend Eric Glomski co-own Arizona Stronghold Vineyard and are touring the country to sign bottles of their finest blends.

Keenan and Glomski then head to Chicago to visit two more Whole Foods locations on June 5 (1550 N. Kingsbury St., 4:30-7:30 p.m.) and 6 (1101 S. Canal St., 2-5 p.m.)

Stronghold Vineyard's mission is to present affordable top quality Arizona wine made by passionate Arizona-based winemakers.

"One of our many goals here in Arizona is to establish a cornerstone around which locally owned and operated, sustainable and organic industries can thrive," says Keenan.

It makes sense that he's partnered with Whole Foods Market for this tour. According to his Wikipedia page, he announced in January his plans to open an organic market in Arizona featuring a tasting room for his wines as well as a food court.

And on the Tool front, it looks as though Chicago's Lollapalooza is as close as we Milwaukeeans are going to get to seeing the band live this year.
