Throughout her years with Alvin Ailey Dance Theater, Jamison continued to perform all over the world. Along with her work with Ailey's company, she also appeared as a guest artist with the Cullberg Ballet, Swedish Royal Ballet, San Francisco Ballet, and numerous other companies. She danced alongside many renowned dancers, including the ballet legend Mikhail Baryshnikov, in a duet entitled "Pas de Duke", choreographed by Alvin Ailey in 1976. Finally, in 1980, she left Ailey's company to perform in the Broadway musical, "Sophisticated Ladies". It was Jamison's first stage experience outside the realm of concert dance, and she admits it was initially very challenging for her. It was a completely different performance atmosphere and required a variety of new skills.
