Def Leppard have launched Behind The Tour 2026, a new video series documenting their latest North American tour. The opening episode follows Joe Elliott on a road trip through the desert, captures the band in rehearsal for their Las Vegas residency, and gives fans their first look at the new stage show. The series kicks off fresh from the band’s “Live at Caesars Palace” residency at The Colosseum, which ran in February and featured a career-spanning setlist alongside some surprises and the live debut of their latest single “Rejoice.”
