here are a few signs i can think of...
- lack of communication. nagtitinginan lang kayo after a song, with that "wtf have i gotten into" look on your face. if there's laughter in between songs, it's forced and artificial. this isn't really a telltale sign, as it may be due to the members having incorrect first impressions about the other, that's why i usually organize a drinking session or similar "bonding" session a week or so before, or immediately after a first rehearsal with a new guy, or new guys...
- nobody seems to be taking anything seriously. i mean, it's okay to have fun during practice, but if you're just cracking wise and/or f**king up the practice material deliberately and/or playing random crap on your instrument without any intention of crafting a serious song, then that means trouble...
- lack of professionalism. people showing up 30+ minutes late to practice (and worse, hindi nagpapaalam na malalate, or malapit lang ang bahay sa studio), people not replying to text messages even if you politely request a reply...these are just a few examples...
since i'm not the most talented musician on earth, i always ask prospective bandmates not to hold their expectations too high. but in any case, if you don't like what you see when you get to audition for a band, or get invited to jam, a little honesty would be much appreciated. don't go 1-2-3 and stop replying to texts. don't make up phony excuses. just let the band in question know, as nicely as possible, that your expectations weren't met and you'd like to try your luck elsewhere.

it always pays to be professional in your dealings with fellow musicians..."good karma", ika nga. we once had a bassist who only lasted one practice with us, and he was honest enough to let us know he wanted to try other options. now his present band is getting a lot of good breaks we could only dream about at this point...
