I think the U2 brand would cost less to produce if Bono et. al. didn't have to be paid. If you took their paychecks out of the cost of their live shows but kept the shows as extravagant, it would be considerably less.

Maybe dead artist will make a come back; like a hologram Beatle's concert. I'd probably go see a hologram Frederic Chopin play his first piano concerto with a hologram orchestra. Or a hologram Beathoven conduct a real orchestra.
