Replicas is an album by Gary Numan and Tubeway Army , released in 1979. It was the second and final Tubeway Army LP , following a self-titled debut the previous year. It was also the first album of what Numan later termed the "machine" phase of his career , preceding The Pleasure Principle and Telekon , a collection linked by common themes of a dystopian science fiction future and transmutation of man/machine, coupled with an androgynous image and ground-breaking synthetic rock sound.
Fuelled by a surprise number 1 hit single, " Are 'Friends' Electric?", Replicas also claimed the top spot in the UK charts.
