yeh people have a habit of taking jokes too far on here. There is only 1 joke that is funny every time i hear it, and thats the legend of Bass Player...
Anyway, i think Still Life is the next port of call. I find it the most similar album to BWP. Deliverance is kind of in a league of its own, as is MAYH really. Orchid and Morningrise are similarish too.
Orchid and Morningrise are kind of technical.. but dont seem to involve me as much in the music. They are a bit.. rougher round the edges. Not as silky smooth as SL and BWP
MAYH is quite brutal but has some really nice bits as well. Its a bridge between MR and SL. Not really surprising given that it came out before one and after the other.
Deliverance has less of the prog stuff in, its more technical death metal with a few soft bits.
Damnation is pure mellow prog all the way through, no death vocals at all.
Id say go for SL, MAYH, MR, O, D1, D2 in that order.
