This concert explores works from Bach's earliest days through the end of his time in Weimar. He was only 33 when he left Weimar, his last position as an organist. Roger W. Sherman is Associate Organist Emeritus of Saint Mark's, after more than 30 years of service to the Cathedral. He is also Artistic Director Emeritus of the Orcas Choral Society. At Saint Mark's, he has served in many additional ways: on Saint Mark's Cathedral Foundation board, on the Vestry (Senior Warden), as President of Cathedral Associates and most recently on the board of the Hallock Institute. Mr. Sherman studied organ, music history and computer science at Oberlin College and Conservatory of Music. His teachers include Fenner Douglass, Arthur Poister and William Porter. He has been featured as a musician on numerous recordings and has concertized throughout the United States and Europe. Since 1993, he has been the host of the popular radio program, The Organ Loft, broadcast throughout the Pacific Northwest. Mr. Sherman is president of The Gothic Catalog. Saint Mark's Flentrop organ is one of the most recorded instruments in the United States. An unusually large mechanical action organ, it has a full-length 32'Prestant and a full-length 32'Bazuin in the pedal. The Flentrop organ benefits from a superb acoustical environment, which was recently improved with renovations to the Cathedral building and windows. After more than 50 years of concerts, service playing and recordings, it remains a landmark instrument, suitable for a wide variety of musical repertoire.
