[6] Lyrically, several songs on Perfect Pitch Black vent about the band's frustrations with their major label stint.

Summing up the review for LambGoat, writer Sean Lioselle said, " This is an odd duck - but not something completely out of left field.

I can't think of a label more suited to release this than Hydra Head - it's pissed, it's slow, it's fairly weird.

"[8] Contributor Cory D. Cyrom was also somewhat positive in an assessment for Pitchfork, concluding "Each of Cave In's albums to date has marked a distinct shift and change of approach, and Perfect Pitch Black's strength lies with their ability to seamlessly intertwine their past and present, experimenting with a diverse array of progressive genres and styles while remaining true to their metalcore roots.

Given the obstacles and challenges of their decade-long career, Perfect Pitch Black is a far more rewarding album than Cave In should rightly be capable of producing this late in the game.

"[9] PunkNews reviewer Brian Shultz also commented on the band's attempt at hybridising their sound stating that "Perfect Pitch Black seems more a stopover in Cave In's progression than anything, as it seems to recall a healthy amount of traits from Jupiter along with fits of screaming and growling, the likes of which haven't been audible since 1999's Until Your Heart Stops.
