The one time I answered an ad in my old hometown I ended up in a great (IMO) originals band. Two years, small tours, an ep and an album. Proud of them, proud of my work with them. Lead singer & guitarist got married, then pg, and decided to settle down near his folks, across the state. We're all still friends.
New town, spent a couple of years in the scene, played (and am playing) with great musicians, but couldn't quite find my musical home. Posted an ad with a very specific description of what I was hoping to find--got a NUMBER of responses that were musically diametrically the opposite of my post. Turned them down. Got trolled by one of the bands... "This guy just doesn't want to play... Bass players ought to be willing to do what's necessary if they want a gig..." Yadda.
Haven't given up on CL, though. Have an audition on Friday for what looks like a perfect opportunity. Guitarist/BL sent all the right signals in his emails; we shared songlists; their sets are just enough challenge for me and seem to balance good music with what the crowd wants... Neither of us were afraid to use real names, share video and audio files, etc.
It's not my dream band (no horns! and not as funky as I was hoping to dig into), but I know my chops, and I think we're a good match. I'll work on the horns angle down the road...
TL;DR - take the chance.
