Diamond Star Halos is the 2022 album from Def Leppard, their first album since their chart topping self-titled record in 2015. It features 15 tracks including the anthemic, stadium-ready singles "Kick" and "Fire It Up," with guest vocals from Alison Krauss on "This Guitar" and "Lifeless. " The album title references T. Rex's "Bang a Gong (Get It On)" with nods to T. Rex, David Bowie, and Mott The Hoople across the album.
