The audience expects familiarity.
Beyond that you gotta tell more. What an audience expects at a pub is different from an outdoor concert is different from a jazz show is different from a coffee-house . . .
As for your point inquiry: I played in a pretty far-out free-jazz band back in the late 80s with
Paul Flaherty. We were booked into a mainstream jazz club. As we walked in the staff realized exactly whom they had hired for the evening. We were fired before we even unpacked!
