Post-tonal Punk

So last night at band practice, I was a little inebriated and I was playing stacatto tritones in the bassline (and distinctly remembering Steve Steiberg, my highschool Jazz Band Teacher telling me to play legato and play the root or the fifth on downbeats) and I think I was in a different time signature than the rest of the band and possibly a different key and all of the sudden I thought,

"If I learned to play Tammy's fretless bass, I wouldn't even need to play in the same tuning system as everybody else."

The only drawback would be if I got addicted to fretless and then Tammy wanted her bass back.
