Not every acoustic-guitar-and-drums duo could open one tour for shock-art rockers Les Savy Fav and headline another with garage-burners the Oh Sees. Not every such duo is the Dodos. The SF band more than holds its own, with energetic shredding, masterful musicianship, and songs that range from spider-walking indie pop to string-rattling blues-punk ragers. The Dodos always showcase deft guitar work, precise percussion, and the kind of stop-start synchronization only duos can achieve. With the Oh Sees. (Neumo's, 925 E Pike St, 709-9467. 8 pm, $10, 21+.)
