I dunno, maybe 3 months, Dr. Eugene? His beautiful cousin left the band a good year ago, I think.. she was the best part of the band.
Either way, Xiu Xiu has always been a joke/novelty band (I don't mean that in a bad way, btw), but used to at least be fun to listen to. I'd put them up there with the Frogs... really ridiculous black comedy stuff. But I just can't get into them at all anymore.. their early stuff is alright but the last 2 albums have been just.. yeah.
