After touring the globe all year playing sold out shows opening for Djo, Post Animal give their new album the deluxe treatment, titling it the Iron Expansion Pack. The Expansion Pack includes two previously unreleased songs Leave Overjoyed and Something Drive which were recorded during the initial Iron sessions.

Iron finds Post Animal reconnecting with founding member Joe Keery (Djo, Stranger Things) and getting back to their roots with all original members writing, singing and performing on the album. Iron marks the first time that all original 6 members entered the studio together in nearly a decade. The product of a few straight weeks together, Iron not only finds them reunited with Keery but is the embodiment of 30 days of camaraderie and unbound musical exploration, their renewed connection ironclad.
