For Flute/piccolo, percussion & piano.  First Edition.  The aboriginal name given to the island of Puerto Rico is Boriken.  This concerto, which bears the same name, presents to us in its first two movements a "sonoric vision" of the Taino native culture.  The third movement exposes a different musical-cultural conception.  The generative element on this third movement emphasizes the European, Spanish and African heritages which predominate in contemporary Puerto Rico.  For advanced players.  Duration: ca. 27'.  Score and parts.
