Some lesser-known gems from the second half of the 20th century are the hightlight of this week's broadcast from the Chamber Music Society.

Highlights include Swiss-born pianist Gilles Vonsattel joining forces with violinist Susie Park and cellist Julie Albers in Jalbert's Trio; the bright young Escher Quartet (pictured) in an excerpt from Bolcom's Three Rags for String Quartet; and a wind quintet of Society regulars in Irving Fine's bouncy, neoclassical Partita from 1948.
