Heartbreaking news from earlier today confirmed that celebrated producer and electronic musician Mark Bell has died. He was just 43.

Warp, Bell's longtime label, announced the news earlier today. The cause of death reportedly stemmed from complications after surgery. In a statement, Warp said; "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."

Bell earned notoriety in the late 1980s as one of the premiere acts in the UK house scene as one half of LFO with Gez Varley. After Varley and Bell separated, Bell continued to work under the name LFO, but added a luminous career as a producer behind well-known acts like Björk in the late '90s and 2000s.

Bell helped in the production of Björk's 1997 album Homogenic, beginning a harmonious partnership that lasted the remainder of his life. He also helped produce albums from Depeche Mode and Deltron 3030.

Producers and musicians poured their respects onto Twitter after the news broke:
