A Musical Quartet

Next, the touching and inspirational documentary "Small Wonders" (1995) offers a look at the work of Roberta Guaspari-Tzavaras, a single mother who taught violin to East Harlem schoolchildren and, when funding for arts programs was cut, fought to establish a non-profit organization to keep her dream of bringing the joy of music to the inner city going. AKA: "Fiddlefest." Four-disc set also includes "From Mao to Mozart: Isaac Stern in China" and "The Turandot Project." 5 1/2 hrs. total. Soundtrack: English.
