Over the course of a career that spans more than 25 years, the Trackmasters have crafted smash hit records for the likes of Michael Jackson, Will Smith, R. Kelly, Nas, Jay-Z, Mariah Carey, The Notorious B.I.G. and so many others. Although their list of collaborators consists of some of the biggest divas, icons, and egos in all of music, Tone of the Trackmasters unveiled that Foxy Brown was the most difficult artist to work with.

“Fox was tough to work with,” said Samuel ‘Tone’ Barnes, as he sat alongside Steve Stoute on an episode of Drink Champs airing tonight (Thursday, Nov. 16) at 10 p.m.

According to the Grammy Award-winning producer, Foxy’s age played a major role in what made it such a challenge to record with her. “She was young,” said Tone of Foxy, who was still a teen when she began recording with Trackmasters. “I think with the stardom coming at her really fast it was hard to get her in the studio and really work.”

He did, however, admit that once the young rap star did hit the booth she wouldn’t disappoint.

“When she arrived at the studio she got busy,” he said. “It was just getting her there on time.”

Foxy’s history with the Trackmasters runs deep. In the early stages of her career, she worked extensively with the hit-making tandem. Tone and Poke handled the majority of the tracks that made the final cut of her debut album I’ll Na Na, including successful records like “Get Me Home” with Blackstreet and the JAY-Z-assisted “I’ll Be.” They were also instrumental in bringing Fox together with Nas, AZ, and Nature to form the supergroup The Firm. The Firm’s debut The Album, which marked its 20th anniversary last month, was mostly produced by the Trackmasters and Dr. Dre.

Besides their conversation about Foxy Brown, Tone and Steve Stoute go in depth on the failure of The Firm, JAY-Z and Nas’ battle and working with a young 50 Cent.

‘Drink Champs’ airs Thursdays at 10 p.m., Saturdays at 12 a.m., and Sundays at 11 p.m. ET on REVOLT TV.
