300 % Density (great CD BTW)... Derek their drummer told me that they're switching it up a little bit every night. He said they may replace "Zombie Autopilot" w/ a song from THE MARCH. However, Buz is not on this tour. A member of Daath if filling in, so I'm sure that limits their possible song list. I was surprised to hear nothing from their 1st album, though.
As for the other bands, I guess it depends if you like them. Born of Osiris was not at my show b/c of weather issues. I liked Impending Doom, but at the same time, all their songs sounded the same. As for Emmure, I don't like them at all, but they drew way more fans than Unearth.
Enjoy the show!
