Severed Heads is an Australian group based and founded in Sydney in 1979 as Mr. and Mrs. No Smoking Sign. The original members were Richard Fielding and Andrew Wright, and were soon joined by Tom Ellard. Fielding and Wright eventually left the group, leaving Ellard as the sole continuing member of the group. A variety of people have played in Severed Heads, including Garry Bradbury, Paul Deering, and Stephen Jones, but over time the group has devolved to Tom Ellard. Early Severed Heads music was characterised by the use of tape loops, noisy arrangements of synthesizers, and other dissonant sound sources, putting Severed Heads in the general category of industrial music
