Scary. I guess you can find weirdos just about any which way. However I connected with two of the bands I regularly gig with through Seattle craigslist (neither has apparently felt the need for legal action against me, at least so far). In fact that's how I happened across the subject posting, I was just idly browsing around to see what other opportunities might be out there.It's not me, but it could be.
I asked an instructor about how to find a band on craigslist in Seattle. He told me a story about how he was in a band that advertised for a player on craigslist. It didn't go well. In fact the band ended up using their limited resources to hire an attorney to get a restraining order against the guy. He advised against craigslist.
