"Dark and twisting, Akrasia refuses to be pigeonholed. Often proggy, sometimes doomy, and other times quite beautiful, it offers surprises around every sudden corner." -Decibel Magazine
"One of the most ferocious things you'll hear in 2014. Immortal Bird have delivered a septic, gnawing, and phenomenal debut here." - Kerrang! Magazine
"Sick and greasy black metal that does an admirable job inventing the sound of a mind tearing itself apart." - The Chicago Reader
"Fresh and uncompromisingly vicious." -Keith Ross, Last Rites
"Immortal Bird cranks out bludgeoning, constantly-shifting grind-laden jams that have a lot of substance to them. For a debut, or any release in a career really, Empress/Abscess is crazy good." -Metal Injection
"For a dark and menacing extreme metal release that's equal parts devastating and memorable, you won't find much better." - Dead Rhetoric
