Rumor has it that Collins hinted about a reunion on his most recent solo tour, so we shall see. Though I agree, probably without Gabriel for sure.
I didn't know they had Invisible Touch Tour on DVD. I just picked up "The Way We Walk" on DVD and was disappointed in the sound quality, but OMG how awesome is the redo of Firth or Fifth from the Old Melody compilation?
IMO Genesis was one of the most underrated bands in progressive rock, but don't get me started
What songs are on the Invisible Touch tour?
