For their twelfth album, Def Lappard have created YEAH!, a heartfelt and hard-rocking tribute to their musical heroes of the late 60's and 70's, the Kinks, Badfinger, T. Rex, David Bowie, Sweet, Roxy Music, Mott the Hoople, Free, Faces and Thin Lizzy. Recording stellar versions of the music that influenced their youth, they have brillantly merged the "now" with the "then" to create a buzz that can only be summed up in one word, YEAH!
