Underworld became one of the most crucial electronic acts of the 1990s via an intriguing synthesis of old and new. The trio's two-man frontline, vocalist Karl Hyde and guitarist Rick Smith, had been recording together since the early-'80s new wave explosion; after two unsuccessful albums released as Underworld during the late '80s, the pair finally hit it big after recruiting Darren Emerson, a young DJ hipped to the sound of techno and trance. Traditional pop song forms were jettisoned in favor of Hyde's heavily treated vocals, barely there whispering, and surreal wordplay, stretched out over the urban breakbeat trance ripped out by Emerson and company while Smith's cascade of guitar-shard effects provided a bluesy foil to the stark music. All in all, the decision to go pop was hardly a concession to the mainstream. The first Underworld album by the trio, Dubnobasswithmyheadman, appeared in late 1993 to a flurry of critical acclaim; the trio then gained U.S. distribution for the album with TVT. Second Toughest in the Infants, the group's sophomore LP, updated its sound slightly and received more praise than the debut. Unlike the first, the LP also sold well, thanks in part to the non-album single "Born Slippy," featured on the soundtrack to the seminal film Trainspotting.
