What album has the most styles?

Martin Barre's "The Meeting" is loaded with rock, Jazz, blues, folkish parts, and all kind of stuff

Time and a word is the one before TYA. I agree but I actually think there's a lot of different kind of stuff on Tormato too. If you can overlook the cheesy keyboard parts there's lots to enjoy on there. :) 

^ I think Steve Howe's guitar has a lot to do with it. He goes from jazz parts to rock parts to country parts then back again. I'm not sure what "clap" is but that adds another element as well. There wasn't really much classical on it. We had to wait for "Fragile" for that. I think TYA might be slightly more eclectic though.

I can only think of a few for now:

Try some Secret Chiefs 3, perhaps Book of Horizons.

Here's a description from Wiki --

Secret Chiefs 3 (or SC3) is an avant-garde group led by guitarist/composer Trey Spruance (formerly of Mr. Bungle and Faith No More). Their studio recordings and tours have featured different line-ups, as the group performs a wide range of musical styles, mostly instrumental, including surf rock, Persian, Arab, Indian, death metal, film music, electronic music, and various others.
