Hi Justin. your response to my last question was super helpful and informative, so i thought i would pose this question to you. I just got back from playing a gig with a local legend of sorts, a singer songwriter who has been doing what he does for over 30 years. i got the call yesterday and received 3 mp3s to learn of his songs to play tonight. no rehersals, just arrive and play. one day notice. I play with the drummer all the time, so we locked it, but i missed a change to a chorus and when the guy called to play a well known cover I had never learned before, i naturally missed a few changes and notes. Over all, under the circumstances, it was a great gig and people loved it. but i feel bad about missing those parts. Often i feel like i "blank out" on a song or two and fudge it up. am i being too hard on myself? Is there some musician psychology to get over trying to play every note correct? Thanks alot, keep up the awesome work.
