Early career Leber's music industry career began with an internship at
Loud Records, working with their street teams. The internship at the
record label led to a role in the label's
marketing department, where he worked with quintessential New York hip-hop artists such as
Mobb Deep,
Big Pun, and
the Wu-Tang Clan. As one of Spears' managers, Leber helped launch her
Las Vegas residency Britney: Piece of Me at
Planet Hollywood in 2013, which grossed over $137 million in its 248 show run. In 2014 Leber teamed up with
Guy Oseary as well as 8 other established music managers and founded Maverick Management, which represents artists from a wide range of
music genres including pop, hip-hop,
rock, and
country. Leber added hip hop artist Lil Nas X to his roster in May 2019, co-managing alongside Maverick's
Gee Roberson. Nas X's single "
Old Town Road" went on to break the record for longest tenure at #1 on the
Billboard Hot 100 in July and earn two wins at the
62nd Annual Grammy Awards. On April 5, 2021, Leber announced that he was leaving Maverick to launch a management and media company Rebel (his last name in reverse) in conjunction with
Live Nation. At his new Los Angeles based company, Leber continues to manage Lil Nas X, Labrinth and LSD among others. In August 2021, Leber and Cyrus parted ways after almost a decade. His work on the show earned him an
Emmy nomination alongside Jen Malone for
Outstanding Music Supervision, and a win at the
Guild of Music Supervisors Awards for Best Music Supervision in a Television Drama. His client Labrinth was also chosen to score the show after Leber played some of his music for the creator
Sam Levinson, and in turn earned two Emmy nominations in 2020 for
Outstanding Music Composition for a Series and
Outstanding Original Music and Lyrics for his song "All for Us".
