Hyper! Norwegian! Electro! Dipteryx! Yay!

I first heard about Datarock from the Web site of Norwegian pop chanteuse Annie, an early supporter and avid fan of her fellow countrybots. The deranged duo of Fredrik Saroea and Ket-Ill debuted with one of my favorite albums of 2005 — the wacky, dancy, preternaturally catchy Datarock Datarock (originally self-released, it's being reissued by Nettwerk Music Group in June). That album's hit, "Computer Camp Love," opens with a call-and-response "Summer Nights" parody set to a throbbing electro backbeat: "I ran into her on computer camp/ (Was that in '84?)/ Not sure, I had my Commodore 64, had to score ... / (Does she have a penis?)/ Seen as supremus, you better know she's a genius and a Venus." Dance to Datarock's electric dreams when the group hits town on Thursday, March 29, at Mezzanine. Admission is $10; call 625-8880 or visit www.mezzaninesf.com for more info. — J. Niimi

Brooklyn's pied pipers Ratatat lure rocker kids into electro and hip-hop territory using crafty trances of delicate melodies and hypnotic power chords. The duo, Evan Mast and Mike Stroud, stays mostly instrumental, but they also have a penchant for remixing rap records; they'll soon release the mixtape Ratatat Remixes Vol. 2 with reconstructions of Notorious B.I.G., Jay-Z, and Ludacris. Ratatat performs with 120 Days and Despot on Friday, March 30, at Bimbo's at 9 p.m. Admission is $16; call 474-0365 or visit www.bimbos365club.com for more info. — Tamara Palmer

Santiago Salazar, aka DJ S2, is a chief operative in Underground Resistance (UR), the Detroit record label revered for its aggressive beats and spiritual melodies. Appearances from the UR roster are infrequent unless you live in Japan; this is the first S.F. gig from one of its members in six years. Bay Area techno producers Jonah Sharp (Spacetime Continuum) and Matt Arnold (Mr. Projectile) will play a live set of unreleased songs without the use of computer software, offering another rare performance on Saturday, March 31, at 536 Stevenson (between Sixth and Seventh sts.) at 10 p.m. Admission is $8-10; call 800-350-3719 or visit www.bassaholicsanonymous.com for more info. — T.P.
