Most of this yr’s deliberate tributes to Beethoven’s 250th birthday have been canceled because of the pandemic, so one welcomed the Sinfonietta’s contribution, which proved characteristically unorthodox. Moderately than supply one thing wholly acquainted, Chen led the Sinfonietta strings in Jeffrey L. Briggs’ association of two actions from Beethoven’s Piano Sonata Op. 13, “Pathetique.” This will have appeared like a little bit of a stunt, in that this music is so inherently pianistic. However there have been new pleasures to be drawn from this association. Within the adagio cantabile second motion (mistakenly recognized onscreen because the third motion), Chen conjured appreciable tenderness and introspection. And within the final motion, the conductor took a slower tempo than pianists normally do, giving the music a level of grandeur it not often receives.
