Vinko Globokar

Vinko Globokar (born 7 July 1934) is a French-Slovenian avant-garde composer and trombonist.

Globokar's music uses unconventional and extended techniques, places great emphasis on spontaneity and creativity, and often relies on improvisation. His extensive output is largely unknown outside of experimental music circles.

As a trombonist, he has premiered works by Luciano Berio, Mauricio Kagel, René Leibowitz, Karlheinz Stockhausen, and Toru Takemitsu, as well as his own compositions. Provided by Wikipedia
