Soon afterwards, the "Tubeway Army" album was quickly recorded by the original line-up and released on blue vinyl. At this point Webb adopted the name "Gary Numan", taking his new pseudonym from a local Yellow Pages where a plumber called "Arthur Neumann" was listed, the singer abandoning the German spelling, to become Numan. Whilst still largely guitar/bass/drums-based, the album saw his first tentative use of the Minimoog synthesizer, which he had come across by accident in the recording studio during the album sessions. Lyrically the record touched on dystopian and sci-fi themes similar to those employed by authors J. G. Ballard and Philip K. Dick, of whom Numan was a fan (the opening lines of the song "Listen to the Sirens" are a direct lift from the title of Dick's book "Flow My Tears, The Policeman Said"). Whilst the album's modest initial pressing of 5000 copies sold out, it did not enter the album charts at that time, and no singles were lifted from it.
