Born and raised in Long Beach, California, Randall Harlow studied the piano from a young age with Nancy Wheeler and, later, organ with David York. University studies have taken him to Bloomington, Indiana and Atlanta, Georgia. He holds a Bachelor of Music degree and Performer Diploma from Indiana University, where he studied organ with Christopher Young, as well as a Master of Music degree from Emory University, under the tutelage of Timothy Albrecht.

An avid traveler, Randall has done summer studies four times at the Calgary Organ Academy International Summer School in Canada, three times at the Oundle Organ Academy in Oundle and Cambridge, England, and twice at the Göteborg International Organ Academy in Sweden. His recent international performances include recitals at cathedrals in England as well as the Festival of Organ and Chamber Music in Sochi, Russia.

As a performer, Randall maintains an intense focus on contemporary music. He has given the world premieres of organ works by Steve Everett, John Anthony Lennon, and Kaikhosru Sorabji. Additionally, he has given premieres in the United States of works by Stephen Ingham and Sven-David Sandstöm. His recent United States premiere of Karlheinz Stockhausen's monumental organ work "Himmelfahrt," the First Hour of KLANG, won the great attention and praise of the Atlanta Journal-Constitution.

Also an avid performer with orchestra, Randall has performed under the batons on Carl St. Clair, John Poole, Imre Paulo, and Richard Prior, including the American premieres of organ concertos by Petr Eben, Tilo Medek, and Giles Swayne. On the lighter side, he enjoys good films, good food, philosophy, and the outdoors, especially the far North. He is in the doctoral program at the Eastman School of Music in the studio of Hans Davidsson.

He became organist for the Penfield Presbyterian Church music program in September '06.
