Tuesday 8/30: It's a super busy night for music in the Twin Cities, with Steely Dan, TV on the Radio and the Script performing separate shows. But we're putting our money on Ke$ha. The Nashville-bred party girl may not have the best voice on the radio, but she knows how to craft a catchy hook, push people's buttons and keep the dance floor jammin'. "Tik Tok," "Your Love Is My Drug" and "We R Who We R" are infectious if disposable fun. Opening is LMFAO, the duo of Berry Gordy offspring who create silly, slacker party pop, including the summer of 2011 smash "Party Rock Anthem."
