During the later touring schedule for "Antenna", Cave In acknowledged the poor reception from longtime fans and began a return to their previous, heavier sound. The group started recording new material in the vein of their earlier style with no label interference, but the less commercial material was received negatively by RCA. The label eventually agreed to release Cave In in 2004 and allow them full ownership to their new demos. This led to Cave In's full re-signing with Hydra Head and the release of "Perfect Pitch Black" in 2005.
