[Rick and Roll]

The two you mentioned are rather obscure and middle of the road for me, but as is my wont, I'll offer my opinion.

The Flower King (just Roine) is real good, very diverse between cuts.

Retropolis is more dark & melodic, especially the beautiful "There is more to this world".

Back In The World of adventures is a must have.

Stardust We Are is my favorite.

Flowerpower is too long, but has some really good stuff on it.

I don't have the live record, but I generally don't do too many of those.

Space Revolver is back to the single disc, but I think it's awesome.

Rainmaker has the Unfold lineup, and I love it. Unfold is more jazzy.
