For those who play music for a living, do you change the tunes you play during each set? If you do two or more sets a night, how many tunes do you repeat? Last week I went and saw Lou Donaldson at the Vanguard. I stayed for both sets. With the exception of one tune, everything else was the same. It was odd. I’m pretty sure he knows more then 9 tunes. It made me wonder why the lack of creativity on his part. He did have a new piano player he never played with before. Could it be the piano player didn't know the tunes? I don't think this was the reason. Maybe at 78 years old, Lou's ability limits what he plays.
