While I agree that the Genesis of the early days was not really a guitarist's band, once Steve left Mike's more direct approach seemed to be given greater visibility. Deep In The Motherlode, Misunderstanding, Abacab, Like It Or Not, Home By The Sea, I Can't Dance and Driving The Last Spike all had celebrated guitar parts.
They were not a guitar band in the early days they were even less so in the later days, when even Phil and Tony played less end edited themselves, refraining from showing-off and sticking to the basics. Celebrated guitar parts? By whom? I haven't heard many Genesis fans celebrating those and none of the critics or general audience ever paid attention to them. Don't take this the wrong way but I find you a bit biased in favor of those bits. You don't seem to care much for Steve's playing but are ready to extoll the virtues of Mike's? Come on……..
