The Human League's second album, Travelogue, was their first to be released in the U.S. (Not that you would have noticed at the time, given the limited distribution; the album subsequently was picked up for reissue by Virgin/Atlantic in 1988.) It was also the last to feature the nearly original lineup of Martyn Ware, Ian Marsh, Philip Oakey, and Adrian Wright. Already, the band's synthesizer textures and Oakey's mannered voice were starting to lean in a pop direction, but much of this album retained the austere tone of earlier synthesizer groups such as Kraftwerk and Tangerine Dream. The conflicting musical directions led to a split in the band after this album, with Ware and Marsh forming Heaven 17 and Oakey and Wright reorganizing a new version of the Human League. Ironically, both ventures were more pop-oriented than before.
