Now, just to make this whole thing more confusing: I heard that there was a hidden "band skill" that apparently goes up if you jam together and that affects whether or not you get gigs. This is unconfirmed, though. Maybe it doesn't affect gig frequency, maybe not. I find the whole thing annoyingly vague. But, my point is, if you have trouble getting gigs, try having your band jam together more often and see if that helps...
