The 90s began as it would go on: with trailblazing, if sonically disparate, albums co-existing peacefully together underneath rock's great umbrella.
As the decade progressed, the sounds creeping from rock's shadows grew more potent. Before we knew it, they'd taken over the mainstream and turned music as we knew it squarely on its head.
As grunge continued its ascendancy, Metallica crossed over into the mainstream and the Prince Of Darkness continued to go it alone. We soon hit the year that (American) punk broke as retro-style Britpop took off in the UK. Elsewhere, as the mid-90s approached, an exciting new cutting-edge genre known as nu metal surfaced for the first time.
By the time the end of the century rolled around, millennia paranoia was rife and alternative music had been through the ringer. There were probably no bands better suited to soundtrack the uncertainty than rock's surviving band of misfits.
The 90s was a time when rock opened its mind to new sounds, new visions, new methods altogether. Music hasn't been the same since.
