Slackers, you caught a break. The 2011 Decibel Festival presents Ladytron at Showbox at the Market tomorrow night, and miraculously, the show has yet to sell out. The Brit-band has an enormous cult following, thanks to several underground hits and extensive touring. And it is beguiling to see them play their sexy Goth-tinged dance-pop live. So buy your tickets now--and cross your fingers that they play a song they often skip--their 1999 breakthrough song "He Took Her to a Movie."
