Def Leppard labored for more than a year to record this, their follow-up to 'Pyromania'. Producer Mutt Lange and the group describe track by track what went into the writing, rehearsing, and recording. Layers are peeled away at the mixing board as we see and hear how their vocal sound, guitar effects, and drums are engineered. Also, they play acoustic versions of two of their biggest hits from the record. As a bonus, an early rendition of 'Love Bites', which thankfully was given a complete overhaul, is presented.
