Well having been listening to rather a lot of Genesis lately and what an amazing band.
I can't think of any band that have had 3 such great era's of their career from the great prog epics of Peter Gabriel era to the commercial pop/rock of Phil Collins era to the slightly darker rock of the short lived Ray Wilson album/era.
Phil Collins gets a lot of slagging but he's one of the best drummers around and a convincing frontman with some incredible songs under his belt like 'No son of mine', 'mama', 'land of confusion' and 'Jesus, he knows me'.
Peter Gabriel is a suitably stunning frontman and singer with an eccentricity that adds to the overall effect.
Ray Wilson is one of the best vocalists in the UK, a great songwriter and a scotsman

- hell i remember going to see his band Guaranteed Pure play Smart Alex's - didn't he do well...
They have a really bad and unfair reputation and are undoutedly one of the finest bands that the UK have produced and certainly one of the biggest.
Well worth getting the platinum collection, 3cds of excellence for a great price.
Cheers
Stuart
