FESTIVAL OF CONTEMPORARY MUSIC at Tanglewood in Lenox, Mass. (July 27, 2:30 p.m.; July 28, 6 p.m.; July 29, 10 a.m.; July 30, 8 p.m.). The Boston Symphony’s concerts in the Berkshires this weekend are fairly routine, but much less so is this annual festival, directed this year by the composer Thomas Adès. Mostly made up of chamber music, the festival includes highlights such as music by Rebecca Saunders, Conlon Nancarrow and Jonathan Harvey on Friday; Judith Weir, Sean Shepherd and Andrew Norman on Saturday; and Gerald Barry, Harrison Birtwistle and Oliver Knussen on Sunday. Monday’s concert involves the Tanglewood Music Center Orchestra playing Lutoslawski’s Symphony No. 3 and Mr. Adès’s own piano concerto, “In Seven Days,” with the soloist Kirill Gerstein. Mr. Adès and Mr. Gerstein, incidentally, appear on Wednesday night in a concert of double-piano music.

INTERNATIONAL CONTEMPORARY ENSEMBLE at Gerald W. Lynch Theater (Aug. 2, 7:30 p.m.). This concert, from the nation’s most important new-music ensemble, asks how pianos and technology can interact. John Adams’s “Grand Pianola Music” uses tape loops; Courtney Bryan’s “Songs of Laughing, Smiling and Crying” involves YouTube recordings; George Lewis’s “Voyager,” in a revised version, relies on artificial intelligence. Beforehand, at 6 p.m. in the Bruno Walter Auditorium, Ms. Bryan and Mr. Lewis are joined by Michael Pisaro and Ashley Fure for a free talk about the compositional process.
