I have just learned that former U.S. Marine Band trombone soloist Robert Isele died on December 8, 2009. The following is from the Marine Band's newsletter, "Notes" (Mar. 2010):

Master Gunnery Sergeant Robert Isele, USMC (Ret.), of Harrisburg, Pa, passed away on Dec. 8, 2009. Master Gunnery Sgt. Isele joined the Marine Band in 1937 and quickly became principal trombone. He was one of the most frequently featured soloists in the band's history. After retiring from "The President's Own" in 1961, he went on to have a successful career in the National Symphony Orchestra.

Isele was almost legendary for his technical and musical abilities. Enjoy this free 1959 recording of Robert's playing with the Marine Band:
