Well, first off I dont like Deicide that much.
There were also having an off night, and on top of missing a guitarist they seemed to be musically a little sloppy. I was tired after Jungle Rot and didn't feel like being thrown around for another hour, and the people I was with weren't really into Deicide. I got a taste of em, and I'll see them again if they come near to where I live sometime, hopefully with a full band, but I had had enough for one night, and so had my friends so we left.
I don't really think I needed to explain it that much though...
