Def Leppard Mfsl

Where Pyromania had set the standard for polished, catchy pop-metal, Hysteria only upped the ante. Pyromania's slick, layered Mutt Lange production turned into a painstaking obsession with dense sonic detail on Hysteria, with the result that some critics dismissed the record as a stiff, mechanized pop sell-out (perhaps due in part to Rick Allen's new, partially electronic drum kit). But Def Leppard's music had always employed big, anthemic hooks, and few of the pop-metal bands who had hit the charts in the wake of Pyromania could compete with Leppard's sense of craft; certainly none had the pop songwriting savvy to produce seven chart singles from the same album, as the stunningly consistent Hysteria did.

While Def Leppard had obviously wanted to write big-sounding anthems on their previous records, Pyromania was where the band's vision coalesced and gelled into something more. More than ever before, the band's songs on Pyromania are driven by catchy, shiny melodic hooks instead of heavy guitar riffs, although the latter do pop up once in a while. But it wasn't just this newly intensified focus on melody and consistent songwriting (and heavy MTV exposure) that made Pyromania a massive success – and the catalyst for the '80s pop-metal movement. Robert John "Mutt" Lange's buffed-to-a-sheen production – polished drum and guitar sounds, multi-tracked layers of vocal harmonies, a general sanding of any and all musical rough edges, and a perfectionistic attention to detail – set the style for much of the melodic hard rock that followed.

MTV had become a major marketing tool by 1984, and the Cars were one of the first bands to use the new video medium to their advantage. The band's fifth album, Heartbeat City (Elektra), spawned several imaginative and memorable videos, which translated into massive chart and commercial success, making it one of the biggest releases of the year. Produced by hitmaker John "Mutt" Lange (AC/DC, Def Leppard), the album included two Top Ten singles - the ballad "Drive" and the charismatic "You Might Think" - plus an additional two that landed in the Top 20: the summer anthem "Magic" and the eccentric "Hello Again"…
