"Rob did an outstanding job leading our aggressive growth strategy in 2020 and for that we are very grateful," says Silbermann, noting that Prinz had a busy 2020, partnering with London based Primary Talent International in March and recruited nine music agents to ICM.
"He and I have been discussing his desire to move back to becoming a full-time agent for a while and while we both now feel that the time right, I am grateful to him for the job he has done."
Also being promoted is Matt Bates, who has been named head of International and Europe.
Siegel has been a long-time agent "for many legendary clients, he has also made it a point to continuously mentor and develop young agents who have gone on to have incredibly successful careers of their own," a statement from ICM reads.
Gibbs, a partner at ICM, is based in Los Angeles and has worked at the agency for 14 years. In August, he was promoted to head of contemporary music and is the highest ranking African American music executive in the agency business, according to ICM Partners. Bates is a 15-year veteran of Primary and has been on its board since 2014.
"Mark Siegel, Robert Gibbs and Matt Bates are universally respected within our agency and the music business at large," says Silbermann. "Through their hard work and dedication to their clients and the team here at ICM, they epitomize the true meaning of leading by example."
Steve Levine will continue to be co-head of worldwide concerts, company officials noted, while Peter Elliot remains managing director of Primary Talent International and Scott Mantell holds the co-head of ICM International title, based in Los Angeles.
The company also announced that it is establishing a Concerts Leadership Committee designed to "keep the department on the cutting edge of every client opportunity and groom the next generation of department leaders," according to a statement. It will include Jacqueline Reynolds-Drumm, Yves C. Pierre, Ari Bernstein and Mitch Blackman.
"We have empowered a talented, diverse and forward-thinking leadership team to best represent our clients and reap the rewards of the investments we have made in the live events business," Silbermann says. "We are all looking forward to a booming 2022 and beyond as the audience returns to experience the artists and concerts they love and have greatly missed."
