The official cause of death for acclaimed music producer Sidney “Omen” Brown has been confirmed, nearly seven months after he was found dead in his East Harlem apartment. According to the New York City Medical Examiner’s Office, he passed away from atherosclerotic cardiovascular disease—a heart condition linked to plaque buildup in the arteries. His death was ruled natural.
As reported by NBC News, Brown, 49, was discovered on September 13, 2025, after concerned family members checked on him when he didn’t show up for a scheduled DJ set at Barawine Harlem, a spot where he had been a regular for over a decade.
Family members previously shared that his passing came as a complete shock. His sister, Nicole Iris Brown, described him as “holistic and healthy,” which made the loss even harder to comprehend.
Professionally known as Omen, Brown spent years leaving his mark on hip-hop, R&B, and soul behind the scenes. The Harlem native built an impressive catalog, contributing to everything from early Roc-A-Fella projects to major releases over the past 25 years.
He worked on records for Memphis Bleek, Amil, Fabolous, Mýa, Redman, and Keith Murray before stepping further into the spotlight with “Tell It Like It Is” on Ludacris’ Release Therapy. The album later earned the Grammy Award for Best Rap Album in 2007, securing Brown his first Grammy win.
Brown later formed a close creative link with Drake through collaborations with producer Noah “40” Shebib, leading to credits on Drake’s “Shut It Down” and Lil Wayne’s “I’m Single.”
In 2013, he added producer, composer, and lyricist credits to Beyoncé’s track “Mine,” featuring Drake, which appeared on her self-titled album. His last credited production came in 2015 on Action Bronson’s Mr. Wonderful.
Nicole Iris Brown shared that finally getting answers has brought the family a sense of closure after months of uncertainty. “I’m kind of happy” to have closure, she told NBC News, while acknowledging the pain of losing her brother remains.
She also noted the family felt relieved knowing there was “no foul play or nefarious things going on.”
While awaiting the autopsy results, loved ones honored Brown with multiple celebration-of-life events at venues where he worked and mentored emerging artists. Another tribute is now being planned to mark what would have been his 50th birthday in August.
