In weather like this, it’s time to enjoy the darkened depths of Houston’s highly air-conditioned cultural institutions. This Friday, June 26, the Contemporary Art Museum presents Steel Lounge Underground with DJ Chicken George, Jeffery Mac, and a live performance by The Tontons. 8-11 pm. FREE! Even colder is the underground meat locker known at the MFAH’s Brown auditorium, which is premiering The Garden by Scott Hamilton Kennedy Friday at 7pm.
