MARLBORO- Artistic directors Richard Goode, Mitsuko Uchida, and more than 75 other master concert artists and exceptional young professional musicians from around the world have been busy rehearsing since June 24 on the campus of Marlboro College. They are spending seven weeks there to form a community like no other, the Marlboro Music School and Festival, led by the two renowned pianists and celebrating its 62nd season. It is a place where musicians exchange musical ideas and make exciting new artistic discoveries as they explore, in a depth not possible at other summer gatherings, some 250 works with the rare freedom of unlimited rehearsal time. Less than 20% of the works rehearsed are performed during the five weekends of concerts.

Of the 80 different works in rehearsal during the first three weeks, seven will be heard on the opening weekend on Saturday and Sunday, July 14 and 15.

Rarely-heard works of Mozart, Schumann, Franck, and Carter are juxtaposed with such favorites as the Beethoven “Ghost” Trio and the Brahms String Quartet in C Minor, Op. 51, No. 1. The latter work was last performed at Marlboro in 1974 with young musicians who went on to become founders or members of the Emerson, Takacs, and Cleveland quartets, and the Boston Symphony. String quartets have not been regular fare at Marlboro in the past.

In addition to the tradition of a master artist in each ensemble, the opening concerts will include pianists Uchida, Jonathan Biss, and Denes Varjon, as well as clarinetist Charles Neidich, and members of the Guarneri and Johannes string quartets. There will be a broad representation of repertoire: vocal music, the all too-rarely-heard Schumann Spanische Liebeslieder, Op. 138, for vocal quartet and piano four hands; a wind quintet that Elliot Carter wrote at the age of 101 in 2009; Mozart’s Adagio and Fugue in C Minor, K546, for strings; and the Piano Quintet in F Minor by Cesar Franck. There will be 28 artists in the two programs with most of the works having received at least 10 rehearsals rather than the one to three of many performances.

The weekend entertainment starts Saturday, July 14, at 8:30 pm at the Persons Auditorium in Marlboro College.
