In a shakeup of the talent agency world specializing in film and TV composers, Robert Messinger has bolted First Artists Management and taken two of his colleagues with him to form Fortress Talent Management.

Messinger, who had been a partner and co-owner of First Artists, will be joined in the new venture by former First Artists agents Rich Jacobellis and Randy Gerston. The agency confirmed the departures but declined further comment. Oscar winners Howard Shore, Mychael Danna and Gustavo Santaolalla are among the composers heading to the new agency.

“We are thrilled to begin this new adventure and to seek out the next generation of great storytellers from around the world,” Messinger said in a statement. “In a time of fundamental change in the film, television and music industries, one thing that remains constant is our commitment to our clients and the value they bring to each project.”
