I’m not sure I necessarily agree. This seems very low risk, safe, and boring for the sake of just doing what the judges like versus doing your absolute best and making it the best show possible. I noticed that Argyle once they moved to 5A, this style does not seem to have the same results.
So effectively, you are arguing that at 4A and below, they should play it safe, do a lot of solos to avoid exposing the rest of the band, and only execute the keys judge requirements. That’s not the music I enjoy, love, or support.
