Pete has had a pretty long career so it's hard to get too specific up front. Which period of work do you like? Late solo, mid-solo, early solo, or his work with Genesis? In the Progressive genre there are several to suggest, but I'd need to know what exactly it is you like about Pete's work. I've been a fan for many years now and I love Progressive music. I would be happy to suggest some if you contact me.
Enjoy
