Too familiar - my guitar player has a stable of gear at home and only brings one instrument to gigs. It gives me a much greater understanding of just what this guy
doesn't know when he says, "I've never broken a string." Very inspiring...
Can't say I'm impressed with this dude not really reacting to what happened at that show until he say how it looked and sounded later on. I've had atrocious gigs where I was really spent from a long day/week, couldn't concentrate on anything, and it showed in both my singing and playing. I was apologizing throughout the whole gig though, as well as after we were done. I felt responsible for not contributing to a decent show 'n all that, but there doesn't seem to be any evidence of that from this guitar player during that show. Everyone has off days, but when they do and act like a walking extended middle finger in the process, that's bad.
I wasn't there to see it, but my first impression is that this guy may be detaching from the band, but not have enough empathy or character to say so. Instead of admitting that he's moving on, he's whimping out and leaving his exit up to everyone else. Like I said, just my first impression, but I've seen this in guys I've played with once or twice before.
Tread lightly and keep tabs on this guys willingness to contribute in the near future. Hopefully it turns into nothing more than an unfortunate speed bump in your success story.
