Robert Urband, a manager of film composers and music supervisors who was as known for his sartorial flair and elegant manner as he was for the strength of his client list, died Monday, April 25, in Los Angeles from lymphoma. He was 63.

Urband, who practiced entertainment law for more than 15 years, managed such A-list clients as Alexandre Desplat, Blake Neely, Ed Shearmur, Javier Navarrete and the late Elmer Bernstein. His first client was longtime friend Michael Kamen, who died in 2003. Others on his managerial roster included music supervisors Nic Harcourt and Thomas Golubic.

Urband “was the lord of my music world,” said the four-time Oscar-nominated Desplat in a statement from London, where he is working on the latest “Harry Potter” score. “Without his bright expertise, his sense of humor, his kindness and his generosity, I would never have become a Hollywood composer.”

Urband co founded the Mr. Holland’s Opus Foundation along with Kamen and served as treasurer for the board of directors.

He is survived by his wife, Lynn Ariail Urband; a daughter and twin sons;, and three grandchildren.
