47. Portishead, 'Dummy'
Portishead don't make dance music, exactly — the torchy gloom beat of Dummy is music for staring into your Rob Roy at 4:00 a.m. and wondering why she needed your wallet to go to the ladies' room. Geoff Barrow mixes a swellegant trip-hop pastiche of astro-lounge beats, plush soul keyboards and spy-movie guitars, with Beth Gibbons belting the bluesy cocktail ballads of a jaded Bond girl. The seductively sleek torpor of "Sour Times" and "Glory Box" has inspired countless imitators, but Portishead got it perfect the first time with Dummy, a bizarre love triangle between a man, a woman and a sampler.
