"Catch Thirtythree" is one 47-minute song divided into 13 sections. It is more mid-tempo guitar riff based, and a more straightforward and experimental full-length album than "Chaosphere" or "Nothing". Nick Terry of "Decibel Magazine" describes the album as a four-movement symphony. Some songs still use Meshuggah's "familiar template combining harsh vocals and nightmarish melodies over coarse, mechanically advancing, oddball tempos", while others explore ambient sounds and quieter dynamics. The first part of "Catch Thirtythree" centers around two simple riffs. In the song "In Death - Is Death", the band uses a combination of noise and silence, which is in contrast with the atypical melodies on "Dehumanization". On "Mind's Mirrors", Meshuggah used electronics, programming and "robotic voices". "Shed" incorporates tribal percussion and whispered vocals.
