Yeah! is the ninth studio album by British rock band Def Leppard. It is the first cover album by the band. It was originally to be released on 20 September 2005, but it was announced on 31 March 2006 that the album would be released on 23 May 2006. The album charted at No. 16 on the Billboard 200 and No. 52 on the UK Albums Chart. Artwork The accompanying booklet contains photographs of the band members recreating classic images from '70s album art. Rick Savage – Freddie Mercury from the album Queen II Vivian Campbell – Marc Bolan from T. Rex's Electric Warrior Joe Elliott – David Bowie from the rear cover of The Rise and Fall of Ziggy Stardust and the Spiders from Mars Rick Allen – Lou Reed, Transformer Phil Collen – The Stooges, Raw Power There are also four group photographs in the CD booklet – on the cover, the centre, inside back cover and the back cover. The inside back cover (back of the CD holder) has a picture with the original triangle Def Leppard logo (from the On Through the Night album), with a shaft of light passing through it and creating a rainbow, a la the cover of Pink Floyd's The Dark Side of the Moon. Reception Rating the album 4.5 out of 5, Stephen Thomas Erlewine of AllMusic praised Yeah! as the band's best effort since Hysteria, noting how the band "no longer sound as slick and calculated as they did on their albums after Hysteria; they sound alive and vigorous, making a convincing case that they're now their own best producers." Erlewine concluded that "few bands could achieve an artistic comeback via a covers album, but as this glorious record proves, there are few bands like Def Leppard."
