Wikipedia : This day (November 29, 1940), in Rochester, New York, is born Charles Frank ‘Chuck’ Mangione, an American flugelhorn player and composer.
Official web site : When Chuck performed in Poland for the 1999 Film and Jazz Festival, his composition Children of Sanchez brought the audience to its feet. Unbeknownst to the composer, the piece had become somewhat of an anthem during the struggle for democracy and many in the audience were in tears, holding their hands over their hearts.
@last.fm : After moving to France in 1968, Mangione led The European Rhythm Machine, a group which tended toward avant-garde jazz. He returned to the United States in 1972 and, after an unsuccessful attempt to establish an electronic group, he formed a quintet which was still performing, with some changes of personnel, in 2004.
