Replicas is the second and final album by Gary Numan + Tubeway Army and was originally released in 1979. It was the first album in what Numan referred to as the “machine” phase of his career. “Are Friends’ Electric?” was a surprise #1 UK hit single and this album was a huge breakthrough. Replicas began as a concept album, based on a book that Numan never completed about a futuristic metropolis where androids with cloned human skin called “Machmen” team up with machines to keep citizens controlled under fear and force.
