THICK SYRUP RECORDS ANNIVERSARY PARTY10 p.m., White Water Tavern. $5.
Thick Syrup turned 2 sometime last December, label founder Travis McElroy reckons. But don't call him a slacker for just getting around to throwing a party. He's been busy: hop-scotching from Little Rock to Austin to Baltimore to work with David and Jad Fair of Half Japanese fame; working the phones and the Internet to reach out to his teen-age heroes — bands and artists like Teenage Fanclub, Sebadoh, Don Fleming and Penn Gillete — for a comp, he's pleased to say, that's coming together; and securing the final tracks for a double CD follow-up to the “Arkansas Compilation” Thick Syrup released in 2007. Two local Thick Syrup acts help him celebrate. The Weisenheimers
, whose self-titled debut came out last year, specialize in cheeky pop-punk. And Frown Pow'r
, who've just put the finishing touches on their debut, make lo-fi (but big energy) garage folk that's made for stompin'. Mr. Bear
, the stage name for singer/songwriter Jack Bishop, opens the show with a big voice, a strong sense of melody and a lot of whimsy.
