In an at-home yet grand setting, the Aulos Ensemble play music the large Bach family might have assembled for its own entertainment.

The Calder Quartet filled in at the San Jose Chamber Music Society in a program of fairly severe pieces that push, in one way or another, at the edge of the quartet idiom practice of their time.

From the U.K., the Carducci String Quartet play Haydn, Mendelssohn, and Debussy in a captivating, clean, clear style.

The always-intriguing Ives Quartet plays a quirky Cowell work, an emotionally gritty Smetana, and an ethereal Haydn.
