When it first aired back in 1988, Mystery Science Theater 3000 represented a bold experiment in television. The whole point of the show was to mercilessly thrash forgotten B-rated films like Santa Claus Conquers the Martians and Eegah!—and the barbs were thrown by one guy and two makeshift robots who lived as prisoners in a space station. MST3K was canceled in 1999, but its creator Joel Hodgson revived the format in 2007 with the live show and DVD series Cinematic Titanic. Now, some MST3K cast members are enjoying a well-deserved victory lap on their latest tour. Last year, the group came to the Lisner Auditorium for a gleeful skewering of the poorly dubbed Japanese sci-fi flick War of the Insects; tonight, they tackle the 1976 horror non-classic Rattlers. It should be an evening loaded with quick quips and terrible dialogue, where yelling at the screen isn’t just tolerated, but encouraged. 8 p.m. at Lisner Auditorium. $25-35. (Matt Siblo)

MUSIC

Canada’s Austra is more than just singer Katie Stelmanis, but it’s easy to see why she’s grabbed the spotlight—-the vocalist was trained early on as an opera singer, and her voice is the kind that seizes center stage. See Stelmanis and her bandmates Maya Postepski and Dorian Wolf perform with Grimes tonight at Rock & Roll Hotel. 8:30 p.m. $12 in advance, $14 at door.

BLOOD, BOOZE, AND BOCCE

Brightest Young Things and the Kennedy Center are cohosting a Lucia di Lammermoor happy hour at the newish Black Jack bar on 14th Street NW. Svetlana Legetic and co. are promising drink specials, ticket giveaways, and bocce. RSVP at Eventbrite. 6 p.m. to 9 p.m.
