The Arion Baroque Orchestra closed its 2012-2013 season with cellist Jaap ter Linden sweetly guest-conducting from the top of a box. It is difficult to conduct through a cello, especially a baroque one held away from the body and resting on the calves, but he made the struggle look elegant and the orchestra appeared to tolerate it. In this, he was helped by pianist David Breitman, who joined Arion for a fine program
at least one piece too long.
