Let there be rock. It hasn't been announced yet, but alt-metal band Tool will rattle the rafters of the Idaho Center in Nampa on Saturday, Dec. 8. Tickets will go on sale Oct. 20 for $39.50 and $49.50 at ICTickets and TicketWeb.

Tool isn't the catchiest metal band on the planet. Songs can go on forever. But there's something about this graceful, vicious group that appeals to almost any headbanger on some level. Tool is arty — yet brutal. Plus, these guys can really play. And Tool concerts have huge psychedelic and prog-metal appeal because of constant trippy visuals.

I remember the first time I saw Tool: They were playing the small stage at Lollapalooza at the Gorge Amphitheatre in George, Wash. I wasn't all that impressed. Then I heard their album. I was impressed. Over the years, Tool have released a lot of cool (and awesomely disturbing) material, but "Sober" will always be my favorite tune.

P.S. Ozzy Osbourne was considering an Idaho Center date this fall around the same time as Tool, then reportedly backed off because Tool might have cut into ticket sales. Nobody messes with Tool. Not even Sharon.
