The Trio has a special celebration planned for Sunday, September 30: the complete Beethoven Piano Trios, performed in a three-concert marathon. While they have given the program elsewhere, this is the first time Kalichstein, Laredo and Robinson — or any other ensemble — has performed all of Beethoven's piano trios in a single day in New York City.

The three concerts begin at 12 noon, 4 p.m. and 8 p.m., with the programs focusing respectively on the Op. 1 trios, Op. 11 and 44 plus the "Ghost" Trio and the "Kakadu" Variations, and Op. 70/II and the "Archduke" Trio. Composer and lecturer Louis Rosen will give a talk beginning 45 minutes before each performance. Tickets are priced at only $10 for each concert.

"Playing and listening to the complete Piano Trios," says Kalichstein, "afford us an extraordinary glimpse of the journey this monumental mind took, spanning his entire creative life: from his pre-Vienna years, through his first published works (the Op. 1 trios), the last work he performed on the piano (the "Archduke" Trio), all the way to the time of the Ninth Symphony (when parts of the "Kakadu" Variations were written).

"To do this in the span of one day," he continues, "following the trios chronologically, is truly a unique experience: a kind of fast-forward view of Beethoven's adult life, with enough time to savor every moment and every piece, yet allowing one to see the entire canvass as a whole, in one go!"

Single ticket sales for the Beethoven Trio marathon will begin later this month. For more information, visit www.92Y.org.
