The lavish, in concert package, which was originally due to launch last month, will be out on 29 May.
The new release features two spectacular concert films: 'Hysteria At The O2' and 'Hits Vegas, Live At Planet Hollywood.'
Def Leppard arranged a marriage of metal and melody to create a sound which ruled the rock world in the 1980s.
Released at the start of the 80s, ‘Pyromania’ made global stars of Def Leppard, setting them on a path of total world domination throughout the decade.
