Gary Numan (born Gary Anthony James Webb on 8 March 1958) is an influential English singer, composer, and musician. Most widely known for his chart-topping 1979 hits "Are 'Friends' Electric?" (when in Tubeway Army) and "Cars", Numan achieved his peak of mainstream popularity in the late 70s and early 80s but maintains a loyal cult following. Numan, whose signature sound consists of heavy synthesizer hooks fed through guitar effects pedals, is considered a pioneer of commercial electronic music.
