I went to see the band at Northwestern, since it was free for students. I also was interested in seeing Gene Hoglan. He looked bored by the material though. None of it was particularly challenging.
I thought the music wasn't too interesting. Not funny enough for a joke band, and not serious enough for a serious band. The whole event reeked of commercialism. For all but the encore, the band was dark, and the lighting was on the animated music videos.
...Trail of Dead was boring and super pretentious art fag music. Not enjoyable.
I had not heard any of the music previously. I assume that those who were familiar with it would be more entertained. The humor sometimes worked, and was sometimes flat. The animated clips in between songs also probably worked better for those acclimated with the series.
