Veteran New York producer Chylow “Chyskillz” Parker recently passed away from a heart attack, according to his friends and family. Most known for his production with Onyx, the accomplished Queens native made a name for himself in the early ’90s with hits like “Throw Ya Gunz” and “Slam” (with Jam Master Jay). Chyskillz also worked with seminal rap acts like LL Cool J and Public Enemy.

“Just got sad news that Producer “Chyskillz” passed away from a Heart Attack. We All Know Him Mainly From His Incredible Production Of The Entire ONYX LP: “Bacdafucup” Which Is A Certified Classic Multi Platinum Album Staple In Our Hip-Hlp Culture… Condolences To His Family… R.I.P. JMJ and BIG DS. Salute Fredro, Sticky Fingaz and Sonny Seeza…,” wrote his longtime friend DJ Premier on Instagram.

Onyx also sent an official message to their fans on Twitter, “We learned today with great sadness of the passing of our brother, Chylow “Chyskillz” Parker. Our love and prayers go out to his family. At this moment and always, we acknowledge his extraordinary contribution to the ONYX legacy, which lives on in the music.”

Even though he's mostly associated with a group as aggro as Onyx, his production style was remarkably smooth:

Public Enemy - Louder Than a Bomb (rmx)
Boss - Livin' Loc'd
Mic Geronimo - Man of My Own
Royal Flush - International Currency

...a song that would fit perfectly on "bacdafucup"

Is that Louder Than a Bomb remix he did the one on Greatest Misses? Loved that shit, and the video too. First Onyx album had some heaters.

weird enough

never got into Onyx

Man this is some sad shit to hear, I friended him a few years ago on facebook, even chatted with him about what he been up to and was saying how he was just getting use to how the industry changed, learning working DAW into his set-up and getting things correct with his royalties, and making new music for a bunch of new artists and his close people like Onyx.

Now none of that is coming into fruition, damn so sad to hear another hip-hop producer/artist is gone.

He was another understudy of Jam Master Jay but now he will get to chill with his homie, rest in power Chylow Parker. :(
