Founded in Denton in 1979, Brave Combo is an early example of musical genre-blurring. Zydeco, classical, cha cha, blues, cumbia, and rock are but a few styles Brave Combo has been known to mash up. “Santa’s Polka” is one of their standards, as is “Hey Little Dreidel.” Sound uncool? Think again. Brave Combo have recorded with Tiny Tim, snagged two Grammys (both for Best Polka Album), had music featured on Ugly Betty, and performed at David Byrne’s wedding reception. $10-$13, 8pm, Sam’s Burger Joint, 330 E.
