In February 1988, Def Leppard was in the midst of their highly successful "Hysteria" tour, promoting their fourth studio album, "Hysteria," which was released in 1987. This album marked a significant turning point in the band's career, solidifying their status as rock legends with hits like "Animal." The live recording from the McNichols Sports Arena captures the band's high-energy performance during a period when they experienced a remarkable resurgence after overcoming internal and external challenges, including drummer Rick Allen's car accident. The "Hysteria" album itself was a commercial triumph, featuring seven chart-topping singles, and its polished production defined the sound of rock music during the late '80s. This concert also showcases the band's ability to engage live audiences, a vital aspect of their legacy, and illustrates their transition into arena-rock superstardom.
