We had something like this here pitched as a Battle of the Bands. You had to pre sell tickets and whichever band sold the most tickets got the best time slots. And supposedly there was a producer and radio play and a free demo recording involved. I wasnt in a band. And I'm kinda old and mostly play in bands that play all covers. But some of the bands was buying the tickets themselves trying to get the best spot. From what i hear it was a gimmick.
