The cause of death for acclaimed music producer Sidney “Omen” Brown has been officially revealed nearly seven months after he was found dead in his East Harlem apartment. According to the New York City Medical Examiner’s Office, Brown died from atherosclerotic cardiovascular disease, a heart condition caused by plaque buildup in the arteries. His death was ruled natural.
NBC News reports that Brown, who was 49, was discovered on September 13, 2025, after relatives went to check on him when he failed to appear for a scheduled DJ set at Barawine Harlem, where he had been a fixture for more than a decade.
Family members said at the time that his death came without warning. His sister, Nicole Iris Brown, previously described him as “holistic and healthy,” making the loss especially difficult to process.
Known professionally as Omen, Brown spent decades shaping the sound of hip-hop, R&B, and soul from behind the scenes. The Harlem native built a résumé that stretched from early Roc-A-Fella releases to some of the biggest artists of the last 25 years.
He produced tracks for Memphis Bleek, Amil, Fabolous, Mýa, Redman, and Keith Murray before breaking into the mainstream with “Tell It Like It Is” on Ludacris’ Release Therapy. The album went on to win the Grammy Award for Best Rap Album in 2007, giving Brown his first Grammy.
Brown later became closely associated with Drake through his work alongside producer Noah “40” Shebib. That partnership led to credits on Drake’s “Shut It Down” and Lil Wayne’s “I’m Single.”
In 2013, Brown earned producer, composer, and lyricist credits on Beyoncé’s “Mine,” which featured Drake and appeared on her self-titled album. His final credited production work came in 2015 on Action Bronson’s Mr. Wonderful.
Nicole Iris Brown said finally receiving answers has brought her family some peace after months of uncertainty. “I’m kind of happy” to have closure, she told NBC News, before adding that it is still painful to know her brother is gone.
She also said the family was relieved to learn there was “no foul play or nefarious things going on.”
While waiting for the autopsy results, Brown’s loved ones held multiple celebration-of-life gatherings at venues where he had worked and mentored younger artists. Another tribute is being planned for what would have been his 50th birthday in August.
