I like a lot of prog bands and LOVE In The Court Of The Crimson King but strangely enough, apart from a few tracks, never got into any of their other albums. Like ELP, Yes.
I also like a lot of good pop bands like The Kinks, Procol Harum and Jethro Tull, but not sure if they are pop or prog but either way I have every album they have made good or not so good. Also like heavy metal specially slightly experimental heavy metal like Enslaved and Meshuggah which I admit are an acquired taste.
As for Genesis it is the Gabriel years for me, I like a few songs with Phil Collins singing but also I like his solo music just can't take to him in Genesis, they went too poppy for me.
I have a lot of Steve Hackett solo albums, a few Peter Gabriel, and assorted albums by the others but if I could only listen to 6 albums for the rest of my life it would be the first 6 Genesis albums every time.
