I'm pretty surprised the Sword is playing the club. Their first album got a fair amount of buzz but it seemed like the second one came and went real quick. I didn't like it at first but I've slowly come to see, via tracks from it popping up in the ol' jogging playlist, that its solid.
Tough to pick between Gary and Sword though. Gary is a show that will likely never happen again, but could be really lame. The Sword will be a guaranteed riffathon but you can probably expect them to come around again in a year.
