Ack! Duke?
I'd have to suggest some of the older, *better* Genesis recodings such as Tresspass (their first and my favorite), Selling England by the Pound, Foxtrot and Nursery Crimes - all are great. The post Peter Gabriel era recordings are good (but not quite as good) up to And Then There Were Three, and I'd certainly recommend any of them. Trick of the Tail and Wind and Wuthering would be my top picks.
As for Duke and the rest....well, only the name seems to have lived on ;-P.
I've been a huge Genesis fan since college and still enjoy spinning their LPs after many decades. I'm sure you'll find some recordings of theirs that will give you the same pleasure.
Enjoy!
