So I need to listen to more Carcass (loving Heartwork and Symphonies of Sickness but having trouble getting into the rest of the albums), try to get into Suffocation and 1349, get some more Rotten Sound and Aborted albums, and pray I have off work.
If you like Heartwork and Symphonies I would guess you would like Necroticism too. But, that's only a guess.
If you want some recommendations for Suffocation go for Pierced From Within, Effigy of The Forgoetten and Despise The Sun.
And you can't really go wrong with any Rotten Sound, but I'd say start with Exit.
Oh, and if you want a recommendation for Aborted, I'd say Goremageddon: The Saw and the Carnage Done. Though I imagine they'd play more of their newer stuff which isn't as good.
