Music Tonight: The "adult" Halloween (this past weekend, mostly at bars) is over and today it's the kids turn. And by kids, I mean those 12 and under. Went and bought a bag of charcoal this morning — I'm giving every Trick or Treater in their teens one fresh briquet. If you're a grown-up sans children (or can get out after the candy-begging ends) and you enjoy Bluegrass (or should I say, "Boo-grass"? No, I shouldn't), head to Covington Mainstrasse's Leapin' Lizard Gallery (726 Main St.) for a a performance by acclaimed Virginia-based ensemble The Dixie Bee-Liners. The band is promising a night of Halloween fun — part of the band's tradition includes performing as the "Zom-Bee-Liners" (see photo) on Halloween, so expect some tricks and treats and lots of excellent UndeadGrass. The band was named the Roots Music Association's 2008 Bluegrass Artist of the Year (beating out Alison Krauss!) and Country Standard Time called the group's 2009 album Susanville "one of the most revolutionary Bluegrass releases in recent memory." The band is working on a follow-up, which they hope to have out in January. The show will be a mix of older originals, new songs and traditional Bluegrass numbers. The show starts at 8 p.m. and admission is $10. Check out the music video for the Bee-Liners track "Heavy" below.
