A close friend and supporter of the Ralston Library, Col. Lowell E. Graham visits the listening room annually to listen to music and offer advice concerning acquisitions and equipment updates.

Lowell has conducted dozens of orchestras and bands around the globe, serving most prominently as the Commander and Conductor of the United States Air Force Band. He is the President and CEO of the John Philip Sousa Foundation and has also served as President of the American Bandmasters' Association. He is currently Music Director and Principal Conductor of the Greeley Philharmonic Orchestra.

Lowell is also one of the most recorded living conductors. Many know Lowell from his landmark contributions to Dave Wilson's Wilson Audiophile Definitive Recordings series. These recordings utilized direct-to-disc mastering techniques, bypassing magnetic tape and delivering a fresh presentation of live sound. Lowell has also recorded for NAXOS, Telarc, and others, and has been the recipient of a Grammy award.
