Chris Kelly, known as Mac Daddy, performed alongside Chris Smith, known as Daddy Mac, in the early and mid-90s.

The duo might be best remembered for the song Jump from their 1992 debut album, Totally Krossed Out, which sold four million copies in the US, hit double platinum and topped the Billboard charts for eight straight weeks.

The 13-year-old rapping duo were discovered at an Atlanta mall in 1990 by then 18-year-old rising star Jermaine Dupri, who helped them to record the aforementioned life-changing album.

In 1992, Kriss Kross landed a spot on Michael Jackson’s Dangerous world tour, as well as a cameo appearance on his popular Jam music video.

Their own music video for Jump shot to number one on MTV and sold over 100,000 copies as a VHS video single.

Their second and third albums also went platinum and gold respectively, but didn’t achieve the success of their first album, due in part to the fact that the teenagers had hit puberty and were marketed with a tougher image.

Kris Kross was also noted for their fashion style, which consisted of wearing their clothing backwards.

Chris Kelly and Chris Smith had reunited once more to star at a 20th anniversary all-star concert honoring So So Def Recordings in Atlanta in February.

“Me and him, we have our times when we don’t talk and our times that we do talk,” Chris Kelly told Yahoo Music when asked about his friendship with fellow rapping partner Smith shortly before their reunion.

“But if it’s any time that I needed him or needed to reach him it was never a problem.”

Chris Kelly had also been broadening his talents, going to back to school to become a musical engineer.

“I just wanted to do something different,” he said.

“Get more on the technical side of things than just being an artist, and produce. I just wanted to be [the] all around best I could be as far as doing everything.”
