Carnival Is Forever is the fifth studio album by Polish death metal band Decapitated.

In 2009, after a period of disbandment, Decapitated's guitarist, composer and founding member Wacław "Vogg" Kiełtyka reformed the band with Austrian drummer Kerim "Krimh" Lechner, vocalist Rafał Piotrowski, and bassist Filip "Heinrich" Hałucha.

[3][4] Decapitated entered RG Studio in Gdańsk, Poland on 9 February 2011 to record Carnival Is Forever, the follow-up to Organic Hallucinosis (2006).

[10] Eduardo Rivadavia of AllMusic said "[...] implausibly heavy, musically vicious and polyrhythmically busy numbers such as "The Knife," "United," "404," and "Pest" (all of which owe a trick or two to Meshuggah, Gojira, and even Byzantine) appear to be at war with themselves—such is the instrumental complexity displayed by each musician as he fights to out-shred his bandmates.

"[12] Scott Alisoglu of Blabbermouth.net also praised musicianship: "In what turns out to be an ace rhythm section, bassist Filip Halucha and Kerim "Krimh" Lechner deliver the rhythmic goods in the form of tight, acrobatic performances and some very colorful percussion that both contrasts and syncs up with all those gouging and biting Waclaw riffs.
