unpopular albums that you really like

I'm sure ITW were like most bands of their sort in getting some detractors when their sound changed, but I never really thought it occurred to the same degree as some of their peers. Either way, Omnio is an awesome record.

I've grown partial to Desultory's "Swallow the Snake" over time even though it's basically their mainstream death 'n roll record. Maybe that doesn't count since they might not have been praised all that heavily even in their death metal years, but whatever.
 
I love Cradle of Filth's first four albums... heck I even like Midian. Also I like just about everything Dimmu Borgir has put out.
 
At the Gates - With Fear (obviously)
In Thy Dreams - Stream of Dispraised Souls EP
A Canorous Quintet - Silence of the World Beyond
Bloodthorn - In the Shadow of Your Black Wings
Massacre - Inhuman Condition EP
Disincarnate - Dreams of the Carrion Kind
 
Pain of Salvation - Scarsick.

I don't know that I can call this "unpopular." It has gotten the band MASSIVE attention in Sweden, it debuted as the #6 Swedish album or something like that - sold more than all of their other albums, got great reviews from critics. It is the longtime fans of the band that were divided by it, and even then alot of us love it.
