Inspired by Bach’s 1723 move to Leipzig, the “imaginative and spontaneous” (The New York Times) Jos van Veldhoven leads the Oregon Bach Festival Period Orchestra and Chamber Chorus through a Baroque-era musical journey. Beginning with movements from Telemann’s celebratory nautical oratorio “Hamburg Admiralty Music,” the program includes cantatas from Graupner and Bach, and concludes with the joyous and transformative Bach Magnificat.
