Buzzed-about Houston band The Tontons (vocalist Asli Omar, bassist Tom Nguyen, guitarist Adam Martinez, and drummer Justin Martinez) deliver a sound that’s proven tricky to describe. At SXSW, their online profile offered “The Tontons don’t have a readily available mainstream band to make an off-the-cuff comparison, so in this space we won’t tell you they sound like Indie Flavor of the Week or Noted and Weighty Classic Rock Name. The Tontons just sound like the Tontons.” Regardless of evident new wave, folk, R&B, and even klezmer inclinations, the quartet (named after those stinky omnivorous reptomammals from The Empire Strikes Back) joins SA’s Bad Breaks in the rock corner of Eye in the Sky Collective’s “Rock vs. Rap” Labor Day Matchup “against” rappers Milli Mars (SA) and Phranchyze (Austin). $5; doors at 9pm Fri, Aug 31; Limelight, 2718 N. St. Mary's, (210) 735-7775, thelimelightsa.com. Check out our full online calendar of upcoming events here: calendar.sacurrent.com.
