If the group isn't there already, High on Fire is at least on the verge of legend status in the world of stoner metal. The Oakland band's latest, De Vermis Mysteriis
, is a sort of concept album - the title is an H.P. Lovecraft reference (or something - it's hard to parse the lyrics over the roaring din of monster riffs). Basically, it delivers more or less the type of sludgy, headbanging goodness that fans have come to expect. Guess what? They're here in town tonight, Monday, December 10, at the Riot Room. With Goatwhore, Lo-Pan, In the Grove, 7:30 p.m., $17.
