Part 3. Exercise
Def Leppard's finest hour. . Predating the whole pop-metal explosion of the later 80's by a few years, Def Leppard's 1983 masterpiece "Pyromania" still is a shining of how metal sensibilities can successfully merge with pop to create something that has integrity, substance and not an inkling of self parody (which Def Leppard would end up falling prety to themselves in a few short years after this album). I became a Def Leppard fan with their 1981 album High 'n' Dry but Pyromania took things to an entirely different level. The songwriting in particular stands as some of the best and catchiest of the 80's (or any decade for that matter). The band never sounded better and this was the last album for a while that drummer Rick Allen would play an acoustic kit on as he hadn't had his tragic 1984 car wreck yet in which he would lose his left arm. Singer Joe Elliot's voice was its strongest as well displaying a great range throughoug the wide range of songs on this album. Guitarist Steve Clark along with Pete Willis (who would be sacked shortly before this album was completed) create a great guitar team. Peter Collen only contributed some solos to this album as he joined really late in the game, but his solo on the track Stagefright (my favorite DL tune of all time BTW) is amazing in both his note choice & chops in addition to his feel. Bassist Rick Savage and drummer Rick Allen create a rock solid rhythm section in the vein of AC/DC and add to the proceedings without drawing too much attention to themselves. Producer Robert "Mutt" Lange would contribue to a co-writer on most tracks in addition to adding a very clean and crips sheen to all of the tracks. This is one of the most well mixed rock/metal albums ever. To be honest, there's not much more I can say about how great this album is that other countless reviewers have already stated. This is Def Leppard at the height of their powers/creativity and unfortunately beginning slightly with Hysteria, the world would see the band crumble into self parody and an endless sea of wretched power ballads. Essential!
