That's perfect - I hope this will become the new trend, so we can slip in later for free for the "dessert" artists
I did something like that at a metal concert some time ago ... wanted to see only one band, did not want to pay the ticket, gambled that they'd play last (and I was right) and sneaked in during the half of the concert since the people at the gate didn't check the tickets so eagerly anymore...
Maybe that is our future of music ... drop by for half a gig because the rest doesn't interest us?
