Born Keith Grayson, in the Graffiti world he was known as "Dez," and was featured in the seminal 1983 Hip-Hop documentary Style Wars. In the DJ and mixtape world, he was known for his "Streetsweeper" mixtape series from the early 2000s. In 2019, Kay Slay released the album Hip-Hop Frontline and the popular "Rolling 50 Deep" and "Rolling 100 Deep" super posse songs and videos. DJ Kay Slay also hosted Shade 45's Street Sweeper Radio on SiriusXM.
Kay Slay's health had been a topic of speculation for months. It was reported in January 2022 that Grayson was suffering from COVID complications, followed by later reports that the DJ was recovering. In a December Instagram post, controversial Hip-Hip promoter Wack 100 suggested via social media that Slay was moments from dying, but the claim was countered by Slay's brother Kwame Grayson. "He's definitely not going to die. He was slowly fading away, but God didn't let that happen," Grayson said told HipHopDX at the time. As recent as last week, Wack 100 said that Slay was "still fighting" and in need of prayers. "He's been off the #ECMO machine for a couple of weeks now," he posted on Instagram. "Let's continue our prayers as our brother continues to fight."
Condolences to Kay Slay's loved ones and fans.
