In 1925, Kahn appeared in a short film made in Lee De Forest's Phonofilm sound-on-film process. Kahn hired many famous jazz musicians and singers of the day to play and sing in his band, especially during recording sessions (e.g.) Tommy Dorsey, Morton Downey, Joe Venuti, Eddie Lang, Artie Shaw, Jack Teagarden, Red Nichols, Libby Holman, Gertrude Niesen, Franklyn Baur, Dick Robertson, Elmer Feldkamp and Gene Krupa. Early on in his career Kahn made several recordings under the name Roger Wolfe Kahn and His Hotel Biltmore Orchestra. It was during September, 1925, that Joe Venuti joined the Kahn Orchestra during their residency at the New York Biltmore Hotel.
