Yeah, first thing he said was "How many damn strings does that thing have?" After the 'groove' comment, we all played a song and when it was over, the other guitarist asked if I had a riff or lick to play around with so I played a funky bluesy thing I had picked around with earlier that day. All the other players on stage start kinda fiddling around trying to figure out a part to play along with me and the drummer piped up and said "Nah, I don't like that, something else, we're not playing that." I think he was drunk or something and maybe thought he was being funny but at that point I packed up my guitar and left. Better than sticking around until I got sucked into a fight with him, lol.
