I voted for Symphonies of Sickness. It was the first Carcass album I heard and the first death metal album I ever heard, so I've got a bit of a soft spot for it.
Necroticism. Carcass are my favouritist band in the world, if youve seen my last.fm i think it comes across there too. Heartwork is the worst Carcass album. Swansong would be second best for me.
1. Necroticism - Descanting the Insalubrious
2. Swansong
3. Symphonies of Sickness
4. Reek of Putrefaction
5. Tools of The Trade
6. SOS Demo
7. Parr-Stree Demos
8. Flesh Ripping Sonic Torment
9. Heartwork
You know, I agree with you about Heartwork. Even though I placed it second last in my list... Which is simply down to the production values on Reek of Putrefaction. Don't get me wrong, I do like both records... but they're definitely both my least favourites. Heartwork has it's moments but to be honest I think it's mostly filler. I actually prefer the pre-Heartwork Parr Street demos!
