Delta Spirit at Emo’s. This San Diego-based band is a perfect mix of old and new — like strong coffee the night after a wild party. On the new ‘Bushwick Blues,’ I hear the Feelies, swear to Dr. Dog. Selfishly, let’s hope they never get too big, because they’ve got such a cool van tour vibe onstage. Welcome home, singer Matt Vasquez, who grew up in Austin and still has family here. With David Vandervelde. $14. 11 p.m. 601 Red River St. www. emosaustin.com.

‘The Bad Plus.’ Audacious and rule-breaking, this jazz trio embraces musical adventure like no others with their inventive re-invention of songs by Nirvana, Aphex Twin, Blondie, Ornette Coleman and the Pixies, among a whole host of pop and rock artists. But spontaneity reigns over calculation when it comes to their live performances, so expect the unexpected. 7:30 tonight. Bates Recital Hall, UT Music Building, 2350 Robert Dedman Drive. $25. www.austinchambermusic.org.
