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. After several releases in that vein, Severed Heads began incorporating various popular music tropes, such as a consistent 4/4 rhythm, strong melodic lines, and resolving chord arrangements. This move was underscored by the incorporation of mimetic devices, such as drum machines. The result was a striking hybrid of the avant-garde, EBM and Synth-pop.
Severed Heads were signed to Nettwerk Records in North America, and Volition Records in Australia, and charted in 1984 with the song "Dead Eyes Opened". This deal lead to a world tour, which was as much a multimedia event, thanks to the video work of Stephen Jones. A period of more or less dance music influenced releases followed until Volition went bankrupt and Nettwerk dropped the band which led to a re-activation and digital distribution via their own Sevcom imprint.
On 4th February 2008 Tom Ellard announced the end of the "Severed Heads".
