WARNING : IF YOU DON'T WANT TO KNOW ANY SUPPLEMENTARY DETAILS ABOUT THE SETLIST THAT HAS BEEN REHEARSED FOR THE TOUR, DON'T READ THE FOLLOWING MESSAGES, THERE ARE SOME SPOILERS !
Plus no major band goes on tour these days without sequencing. That might be okay for the Spice Girls but It sounds too robotic.
It's true, but usually "sequencing" are in fact pre-recorded tracks (backing vocals, supplementary keyboard sounds, usually coming from the album multi-tracks...). But you're right, for nowadays pop bands, because people usually want them to sound exactly like the record. That doesn't mean they don't play a single note on stage. Even Peter Gabriel does it now (for certain keyboard parts, e.g No Self Control, but that doesn't mean he doesn't sing for real, and that none of his musicians plays for real over these tracks...).
But to my knowledge, Phil Collins never did that (what we hear on the Not Dead Yet Tour is all played for real, no supplementary sounds or sequences needed).
And I don't think Genesis will do that either.
Because of that, drummers now need a metronome track to start exactly at the right tempo.
Nic is just diddling about over the top of sequenced beats most of the time!
If you talk about drum machines (Mama, Invisible Touch), ok, but again that doesn't mean that what he has to play is that easy... "Mama" drum part is not "just diddling about over the top"...
Drum machines are the ground for some songs, but you still have to build the house on it.
