Leo Brouwer (b. 1939) is a Cuban composer, guitarist, and conductor. Born on 1st March in Havana, he went to the United States to study music at the University of Hartford, and later at the Juilliard School, where he was taught composition by Stefan Wolpe. Brouwer's early works show the influence of Cuban folk music, but during the 1960s and 1970s he became interested in the music of modernist composers such as Luigi Nono and Iannis Xenakis, using indeterminacy in works such as Sonograma I.
