There is a menacing, dissonant, raw sound that fills every song on "Comfort". It is Failure's least accessible album, their loudest, and possibly their best, yet it gets overlooked most of the time due to the production. It's not even bad production though--only slightly muddier than their other two LPs.
I think it is best listened to once you've explored Failure's later work. Once you're used to the band and the kinds of musical signatures they employ, you'll really be able to appreciate what they did with "Comfort".
