I think it's definetely possible for Genesis to make a reunion. At this
point, I think as old men, all of the members of Genesis wouldn't
really feel the need to produce any pop music to appease the billboard
charts and the general masses. What's the point in trying to sell your
self as pop rock group of 60-somethings and 50-somethings?
I agree with sleeper and Moogtron, that I hope that they do the logical
and fair thing and try going back to a "progressive rock" style. I
don't really expect anything that is totally like Pre-Wind and
Wuthering, I mean Genesis could take on avant garde music or jazz
fusion and I wouldn't really mind; in fact I'd love it! I think they've
been avoiding the fans who loved the original line-up. Genesis just
doesn't feel complete without the whole team.
And besides, just because time suggests that the pattern will never
change, once you've been "progressive" you'll NEVER be "unprogressive."
