Best Progressive Death Metal Albums

I'd put this above Blackwater Park which in itself is a masterpiece - in fact, every Opeth album pre-heritage is essential to this sub-genre. Their newer style although not my cup of tea, but still rocks hard. Opeth never disappoints.

Greatest of all. The best concept album I've listened to in a while.

Magnum Opus for Opeth

Death/Progressive Metal Masterpiece!
