Producer Chyskillz, the mastermind behind the classic Onyx singles “Slam” and “Throw Ya Gunz,” passed away from a heart attack on Tuesday (February 13).

In a joint statement to HipHopDX, Onyx MCs Fredro Starr and Sticky Fingaz said, “Rest in Paradise to our brother Chylow ‘Chyskillz’ Parker. Our condolences go out to his family and close friends. We will always acknowledge your contribution to the Onyx legacy. Your music will always inspire. Love our brother!”

Although Chyskillz is widely known for his contributions to Onyx’s platinum-selling debut, 1993’s Bacdafucup, he also produced for other Hip Hop legends like Run-DMC, LL Cool J and Public Enemy.

Several members of the Hip Hop community — including former Onyx member Sonny Seeza, DJ Premier, DJ Eclipse, De La Soul’s Maseo and Jedi Mind Tricks’ Vinnie Paz — paid their respects on social media.
