A Little Night Music: Calder Quartet

Music, Classical and opera
Mostly Mozart Festival. This superb young Califonia foursome comes to the tony Kaplan Penthouse for a late-night concert of the kind that this festival has favored lately. There's no Mozart on the bill, just a pair of profound works by composers who followed in Mozart's footsteps: Thomas Ad├Ęs's Arcadiana and Beethoven's String Quartet in C-sharp minor (Op. 131).
