This is the second of four volumes of the complete recorded output of Def Leppard available as both a 10-LP, 180gm vinyl box and a limited edition 7-CD set featuring all the recordings from the band in the 1990’s with their original packaging. The albums were re-mastered by Ronan McHugh at Joe’s Garage and cut by Greg Moore.

Def Leppard - Volume Two features 1992’s Adrenalize, which topped the charts in 23 countries, debuted at #1 on the Billboard 200 chart and #1 on the UK chart, and features songs such as “Let’s Get Rocked,” “Make Love Like A Man,” and “Have you ever Needed Someone So Bad,” 1993’s Top 10 release Retro Active, the bands first compilation featuring B-sides and previously unreleased recording sessions from 1984 to 1993, Def Leppard’s sixth studio album Slang, released in 1996 and the first full album to feature guitarist Vivian Campbell, and, making its vinyl debut, 1999’s Euphoria, which also went Top 10 on the US and UK charts and marked the bands return to their signature sound and features the hit “Promises.”

Also included are Rarities Vol. 2 and Vol. 3, both specially compiled by Joe Elliott containing more rare B-sides and live recordings from the 90’s, complete with newly commissioned artwork.

Housed in rigid boxes, Def Leppard - Volume Two also contains a 40-page hardbound book packed with rare photos by Ross Halfin and introductions written by the entire band.
