Thought this might turn into an interesting thread. Basically, what's a band that completely blew away your expectations when you saw them live? Either you expected them to be great and they were terrible, or you expected them to be terrible and they were great, or you expected one genre and got something else
For me, I saw a show a few years back and these guys were one of the openers. They came out with a hip hop intro track and broke into the song featured in the second half of this video (couldn't find a video of exactly what I saw, but this should give you an idea of how the show went).

Needless to say, I was expecting to have to sit through a generic hip hop set of some sort, and instead ended up with a full set of decent, catchy punk with great live energy and solid playing.
Mordred on the In this Life tour. I was a fan of the band, but their performance was just mind blowing. Perhaps the best show I've ever seen, and I've seen hundreds.
