After a fairly bare concert week to this point, tonight offers two great live music options. (There were three, but the Southeast Engine/Frontier Ruckus show at Andyman's Treehouse got moved to Sunday.)

First, consider Russian Circles (pictured) and Dalek at Ravari Room, 2657 N. High St. Doors open at 9 p.m. for this $10 show, which also features Young Widows and Heady Nuggets. I previewed the show in last week's paper, but in case the preview disappears from that link, how about a reprint?

This killer double bill is the latest example of how Ravari Room has been helping to pick up the slack since Little Brother's closed. Russian Circles aren't as well known as fellow guitar instrumentalists Explosions in the Sky and Pelican, but they might be the best of the bunch. Their pogo-powered shredding and discordant chord changes liken them to a more metal version of locals Six Gallery, building rock songs that could work with vocals but survive just fine sans singing. Co-headliner Dalek drops deep, booming intellectual verses over thickly layered, grimy electronic soundscapes, recalling Trent Reznor's work with Saul Williams or a chopped and screwed take on the Bomb Squad's Public Enemy productions. Keep it up, Ravari.

The other big one is Los Angeles noise/disco/fashion ensemble HEALTH at Cafe Bourbon Street, 2216 Summit St. They're joined by two local acts that sound like the weight of the world bearing down upon you, Sword Heaven and Muscle Puzzle. That one starts at 10 p.m., and though I don't know what it will run you, I suspect $5-$10 is a safe wager.

And of course Lost (9 p.m., ABC) is on! Kate episode tonight.
