I think the drummer has thought...too much guitarists who say me what I have to do and play, this guy have exaggerated with time changes...the pay don't worth the efforts...from now I will play the same 4/4 for everyone!
Actually i thought something similar ... a show like this is a dangerous job for the drummer. He only get noticed when he mess up otherwise everybody only has eyes and ears for the guitar player.
I have to admit that i feel a bit sorry for the drummer .. on the photos he seems to be a nice guy.
