What’s with Caveman and surprise shows on the Bowery? Last time we caught them it was at a “super secret” gig at R Bar, and now Bowery Electric tweets us to say: “TONIGHT: @CavemanBand surprise performance @boweryelectric, Starts at 7:30, $10 tickets at the door only!”

Icewater will open, according to that band’s Twitter.

Anyway, you can add this to the rest of this week’s Good Shows. If you get in, say hi to drummer Stefan Marolachakis and order the band’s favorite drink, The Gauntlet: a shot of whiskey, then a shot of vodka, then a shot of tequila — all consumed as quickly as possible.
