Pioneering music producer Mark Bell, half of the British electronic duo LFO and regular collaborator with Björk and Depeche Mode, has died, his record label has confirmed.

Warp Records confirmed the news “It’s with great sadness that we announce the untimely passing of Mark Bell of LFO who died last week from complications after an operation. Mark’s family & friends request privacy at this difficult time.”

LFO, which Bell formed at the start of the 1990s with his Leeds university friend Gez Varley, kick-started the decade’s love affair with electronic music, from techno to acid house. The duo’s eponymous first demo, LFO, went from club staple to top 20 single in the summer of 1990.
