Leslie has been credited on albums by Britney Spears, Beyoncé, Chris Brown, Diddy, LL Cool J, Kanye West, and Usher, among others.

[1] Leslie was born in Richmond, Virginia, and relocated homes frequently due to his parents' jobs as Salvation Army officers.

Leslie suddenly saw a new future for himself when a friend played him a Stevie Wonder CD freshman year,[6] and began spending time at the on-campus recording studio.

[7] Eventually, Leslie moved back home with his parents in Phoenix where he convinced them to take out a $15,000 loan for a production studio so that he could pursue music full-time.

The soundtrack was supervised by Sean "Diddy" Combs, who was impressed by Leslie's production style and offered him a management contract upon meeting him.

[8] Under the management of Combs, Leslie worked on various Bad Boy Records projects, including releases from Loon, Cheri Dennis, B5, New Edition and Danity Kane.

[10] His third single, "How It Was Supposed to Be" was released with two music videos: a rock version and a military take on the song, which was Leslie's directorial debut and was co-directed by model Tyson Beckford.

[15] While working as a producer, Leslie went on to create NextSelection Lifestyle Group, his music-media company he founded with online marketing partner Rasheed Richmond.

Her breakout smash "Me & U" (written and produced by Leslie) spent 20 weeks on the Top 40 and went on to reach number three on the Billboard Hot 100, selling over a million digital units.

[18] After releasing Black Mozart in 2013, the album rollout strategy galvanized him to start SuperPhone, a direct text marketing service.

[1] In subsequent months, musicians such as 50 Cent, Raphael Saadiq, and Talib Kweli would use the underlying technology to launch their respective upcoming studio albums and power their own music membership clubs.

"[20] Leslie's work with SuperPhone has been supported by venture capitalists such as Ben Horowitz,[21] journalists such as TechCrunch's Josh Constine,[22] and musicians such as Kanye West.

[23] Miley Cyrus, Zayn, Silk Sonic, Ava Max, and Cardi B have employed SuperPhone direct-texting marketing methods.

[25] He attributes Michael Jackson, Prince, Jimi Hendrix, James Brown, Quincy Jones, The Beatles, and D'Angelo as musical heroes as well.

[27] Leslie often documented his interaction with his audience, including giving away free iPods,[28][non-primary source needed] backstage passes to his concerts,[29] and invitations to have dinner with him.
