The Orpheus Chamber Orchestra welcome guest pianist Christopher Tyler in a live performance Friday night at 8 pm on Classical 90.5. Called “The New Brandenburgs”, the program features Aaron Jay Kernis’ Concerto with Echoes, Melinda Wagner’s Little Moonhead, Sir Peter Maxwell Davies’ Sea Orpheus, Christopher Theofanidis’ Muse, Stephen Hartke’s A Brandenburg Autumn and Paul Moravec’s Brandenburg Gate. All the works were inspired by the Brandenburg Concertos by Johann Sebastian Bach.
