They have developed a repertoire of great variety, and have performed in Japan, Western Europe, Israel, Alaska, Hawaii, Costa Rica, continental United States, and on several cruises.

As an oboe soloist, he has played at New York’s Caramoor Festival, Lincoln Center, Kennedy Center, Hollywood Bowl, Carnegie Recital Hall, and at the Los Angeles Music Center. His first of many solo performances with the Philharmonic was in 1962 when he was fifteen years old. David is a faculty member at the University of Southern California Thornton School of Music, and has also taught at Vassar College, Duquesne University, and the Sarasota Music Festival. He is in demand as a clinician and judge for such notable events as the American Oboist, New York Oboe International Competition, Gillet Competition, and has given master classes at the Manhattan School of Music and New England Conservatory. 2002 marked his first year on the faculty of the Music Academy of the West in Santa Barbara, California.

David is also an internationally recognized master of the musical saw. He has been featured on the Tonight Show, Prairie Home Companion, at the Hollywood Bowl, and in television commercials and movies, including the Grammy-winning sound track to "O Brother, Where Art Thou?"
