unpopular albums that you really like

Arcturus-La Masquerade Infernale, The Sham Mirrors
Eucharist-Mirrorworlds
Any Necromantia
Death-Symbolic
Cadaver-Necrosis(don't love it, but like it)
 
I wouldn't call these unpopular. Sideshow Symphonies you could argue was unpopular, but the two you mentioned are the band's creative pique.
Perhaps, but I'd say that on this board these albums aren't exactly top picks. And Arcturus' debut which is actually considered by many a classic of the genre or at the very least, their only worthwhile release is the one I don't like.
 
Bathory - Destroyer of Worlds (I actually like most of it, not just the songs with the early '90s sound)
Arcturus - Sideshow Symphonies (pretty much the only Arcturus I care about)
Megadeth - Cryptic Writings
Megadeth - Risk (about half the album)
 
^ Yeah, an incredible piece of work.

Trust is my favorite Megadeth song. That track is a fucking monster.

This isn't unpopular, at least not in my experience. Great album as well.

Eh, doesn't have great ratings on M-A (I know, it's MA and there are a fair number of 'tards on there, but still) and I've talked with some people from here and they've said it isn't a GREAT album, but I like it.
 
Ah, I'm probably confusing boredom with dislike in this case.

That's true though, I think one person on here ridiculed me because I was listening to Decapitated one time. Forget who it was though.
