There's the music, the hang, and the gig.
try to get any two of the three.
That's kind of the Stage 1 filter for me….except its "music, hang, money".
Then it's: "musicianship, bandsmanship and showmanship"* for any band that intends to gig.
* I haven't figured out a gender-neutral wording that rolls off the tongue and is reasonably well defined, so don't beat me up on that!
