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, which these three albums comprise. The song “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.
