A couple highly anticipated rock shows that couldn't be much more different are the main course on tonight's live music schedule. First up is Thee Silver Mt. Zion, who come to Skully's Music Diner, 1151 N. High St., for an all-ages extravaganza. The sprawling Montreal ensemble has roots in Godspeed You Black Emperor!, but their pop-damaged, vocal-centric epics, weird and political though they may be, aren't much like what that their parent band used to do. Read my preview for further explanation, then get to the show. Tickets are $14 at the door, but Magnolia Thunderpussy might still have some $12 presale passes this afternoon if you hurry. Doors open at 8 p.m., the gorgeously sleepy songs of Eric Chenaux begin around 9, and A Silver Mt. Zion is expected to be done by midnight.

That gives you enough time to get up to Cafe Bourbon Street, 2216 Summit St., and see Mudhoney. It will be quite a privilege to see the grunge Godfathers pack their monstrous sound into the close confines of Bourbon Street. If you show up late (or even if you're there when the doors open at 9 p.m.) you'll want to get to the bar during happy hour to make sure you get one of the $20 tickets. Of course, showing up late for the show would mean missing the great Grafton and Cheater Slicks, and if you know how Mark Arm feels about Cheater Slicks, you know missing them ain't smart.

So you've got yourself a choice. But more choices should be as good as this one.
