they put on an entertaining show, for sure....definitely would have had more fun if i'd had the chance to hear GK beforehand though. Christofer said afterward, though, that he was disappointed with their performance....he said he and 2 of the other permanent members (i think the bassist and drummer) played like shit, and he said that they sounded the worst they ever have since '98 when they started working with this sound guy, and that the sound guy agreed.
that said, not being familiar with the stuff, i didn't notice so much, and since the sound at Jaxx is usually not that great (but better than the last time i was at the Palladium...), and having not seen them before, it wasn't that easy for me to judge on their sound in a relative sense.
