ROS had three of its own productions this busy season: in October with music of Gabrieli, Bruckner, Mendelssohn, Beethoven and more; in March with music of Monteverdi, Handel, Gabrieli, Bach; in May ROS presented the U.S. premiere of Vaughan-William’s Five Tudor Portraits in its special chamber-ensemble setting, along with the local premiere of Arthur Bliss’ Pastoral: Lie Strewn the White Flocks. ROS also was guest of the RPO in December for Handel’s Messiah and invited back in May as part of the surprise farewell following Christopher Seaman’s final concert as RPO Conductor. Eric Townell led the RPO orchestra, ROS and the audience with processional singing of “Pomp and Circumstance” with special lyrics by Peggy Savlov for the occasion.
