Symbols, by KMFDM. I only say this because I've listened to that album more than anything else by KMFDM, and since they're my favorite/most respected band, I'm going with that.
Noooo, noooo! That is ...
wrong! For KMFDM, it has to be Nihil! Although I just used to have one cassette with Nihil on one side and Xtort on the other, and just play them continually on repeat, so I barely distinguish between them. Although Symbols is great, it's a huge step down from that apex.
"Dark Side of the Moon" - - by Pink Floyd
Yeah, I'm going to go with that myself. It's one of the very few albums that could truly be described as "flawless".
My "runners up" would include NAIL by Foetus, Pandemonium by Killing Joke, OK Computer by Radiohead and Screamadelica by Primal Scream - again, all records that could reasonably be described as "as perfect as music gets".
