Your favorite prog rock music? ?

if you're ok with ebay -
This ("Out of the Mist") is probably the best album from that group:
Out Of the Mist

Here's a copy of the very first Renaissance album:
Renaissance

If you want to get the first two (Original Line-up) Renaissance releases on 1 CD plus some bonus tracks, there's this:
Renaisance Innocents and Illusion

The vinyl of "Out of the Mist isn't bad, but the original Renaissance albums pressings leave a lot to be desirred, so CD may be preferred.

The other great thing about this group is John Hawken (ie the KB player from Strawbs) is a big part of it.

Thanks, Bd! I'll check these out.

I too like Man but my favorite recording is the live set "Maximum Darkness." John Cippolina's guitar work is really tasty.

Add "Porcupine Tree" (any and all albums) to the list.
