Larry Rosen (1940-2015) was a music producer who, in the late sixties and early seventies, formed the New York agency Duo/Creatrics, Inc., which primarily supplied music to advertising campaigns as well as some film projects. Rosen scored animated segments for the third season of Sesame Street with agency partner Shep Meyers (variously listed in registration and CTW documentation as Charles Myers, Chuck Myers, and Chuck Meyers).
In 1972, Rosen and Meyers produced singer Jon Lucien's album Rashida. Rosen moved away from advertising and with Rashida conductor Dave Grusin formed Grusin/Rosen Productions (GRP) in 1976. GRP, which eventually became its own label, produced recordings with Earl Klughe, Willie Nelson, Judy Collins, Billy Taylor, B. B. King, and Diane Schuur. He later organized jazz concerts and produced the PBS series Legends of Jazz.
