Check out Nathan Laube performing on a four-manual, 120-rank Goulding & Wood. If you're confused, he's an organist and it's an organ, respectively. Laube is assistant professor of music at Eastman School of Music in Rochester, N.Y., and one of the most respected organists in the country (he's performed several times in Pittsburgh, which has a low-key killer organ scene). The program at East Liberty Presbyterian Church includes a premiere performance of a composition by Craig Phillips, as well as pieces by Charles-Marie Widor, Jean Roger-Ducasse, Healey Willan, and Richard Wagner.
