Young girls dancing. To jazz. That was the kinetic scene this week upstairs in the Continental Gallery, and indeed, Dr. James Polk’s rare Hammond B3 organ playing does that to people. As does the whole of the Elias Haslanger Quartet. The native Austinite and bandleader blows Wayne Shorter; covers Cap City jazz landmark Kenny Dorham, Horace Silver, and Billy Strayhorn; and unleashes six-string sluicer Jake Langley every Monday – free. Yes, Virginia, Free Week continues every week, 8:30pm. Tip your band and bartenders. – Raoul Hernandez
