The Richmond-based rock duo Boxwave features John Mustachio on bass and Brad Ellsworth on percussion in a minimal act that strives to invigorate the often ignored rhythm section. Spartan and unassuming, Ellsworth provides enthusiastic backing to Mustachio’s gritty playing in a guerrilla rock attack that fuses funk and jazz into extravagant, melodic flights. The pair appears to have just picked up what was found on the stage, and yet they confidently cover Rush’s “Tom Sawyer” using only inspired bass flourishes and pocketed drumming.
Saturday 1/11. Free, 10:30pm. The Whiskey Jar, 227 W. Main St., Downtown Mall. 202-1549.
