This is a major event in the classical-music calendar, first held in 1946, with a wide array of international participants. Guest stars this year include Lang Lang, Daniil Trifonov (winner of the 2011 Tchaikovsky Piano Competition), countertenor Andreas Scholl and Violeta Urmana, a soloist with the New York Met. 

The Weekend of Czech Chamber Music will take place on the last weekend of May, with 11 chamber-music concerts at various historic Prague venues, many of them not usually open to the public.
