The Harvard Summer Chamber Series opened its third season Monday night and was lauded in the Boston Globe for the "exalting" performances heard that evening. As in previous years, the group is composed of a nucleus of about live professionals well known in the Boston area surrounded by young artists from Harvard, Curtis, New England Conservatory and U.S.C.

In case you missed the first round, you can catch them again this Monday right--in fact, for the next six Monday nights all in the newly air-conditioned and efficiently soundproofed Sanders Theater.

Guest violinist Donald Weilerstein of the Cleveland String Quartet is back making a guest appearance with the group again this summer, and will perform in Schumann's rarely heard piano quartet. Also light works of Weber Leon Kirsohner, music professor at Harvard and director of the Chamber players.

Summer school students who show up with an ID at the box office on Monday night or in advance can purchase tickets at a reasonable half price. Monday, July 14, at 8:30.
