There's a small heap of them. Yesterday, I listened to Quiet Sun's album "Mainstream" .. another I've yet to see mentioned here.
Of Caravan, of course the whole grey and pink album is awesome. I also thoroughly enjoy For Girls Who Grow Plump in the Night although I try not to overplay it.
I've also fallen a bit in love with Camel's "Music Inspired by the Snow Goose" lately.
