Aerosmith had a penchant for the unusual or dreamy-eerie intro:
There is a dubby-metal thing going on at the start of these near-contemporaneous MTV faves by Guns N 'Roses and Def Leppard:

The Drum and Bass Intro could be one of the worst things ever, especially during the Intelligent Era - every bleedin' track came with a long drawn antechamber of synth-pads and atmospheric flatus.
