Jonathan Biss was one of a number of musicians who turned out to hear György and Márta Kurtág perform at Zankel Hall on Sunday night. Also in the crowd were Richard Goode, Leif Ove Andsnes, Christian Tetzlaff, and Ursula Oppens. Biss offers "fugitive thoughts" on his website. I wrote about a Vienna version of this stupendous program in 2006.
Sonatina from Bach's Cantata BWV 106, "Gottes Zeit ist die allerbeste Zeit," arr. György Kurtág; G. and M. Kurtág, upright piano; BMC CD 123.
