Musical mistakes? Sure, I try to maintain an eclectic mix of at least forty minutes of canciones, polkas, redovas, marchas and valses with tasteful, original licks on button accordion in the tejano "Conjunto" tradition, twenty 1920's pop songs on banjo ukulele, four or five andean songs/instrumentals on quena and a couple of chinese tunes I do on new years eve. Believe me that's a mistake if like most musicians you just want to make a couple of bucks, get stoned, or get laid! That's really all I ever REALLY wanted-on a higher, purer level, but the same thing.
