Morningrise was where I discovered Opeth. Love it to pieces, but BWP is their pinnacle which extends through the twins of Deliverance and Damnation. @markm, id hesitate to reconsider your back catalog rule with any other band, but Opeth is different. Everything they did from the first album through Ghost Reveries is worth your time. My Arms and Orchid both have some real gems. The Baying of the Hounds, Face of Melinda, The Moor... just so many great tunes.
