  1. Complex

    Complex is a song by British musician Gary Numan. It was the second single to be taken from his 1979 album The Pleasure Principle. The single reached number six in the UK Singles Chart. The recording's backing track uses conventional acoustic drums, acoustic piano, and electric bass guitar, however the distinctive lead parts are performed on violin, viola, and heavily flanged and reverberated analogue monosynth, an unusual combination in popular music. Lyrically, the song alludes to a psychological complex, expressing a paranoia that might have been directed at critics, fans, stalkers or false friends, depending on one's point of view: Please keep them away Don't let them touch me Please don't let them lie Don't let them see meA BBC Radio 1 review panel speculated that this song was "the first electronic ballad", although this is untrue, as it post-dates recordings such as "Hiroshima Mon Amour" by Ultravox and "Neon Lights" by Kraftwerk by a couple of years.
