The Schuller festival, which began yesterday, also includes free concerts at NEC's Jordan Hall tonight and tomorrow and a talk at Harvard University tomorrow afternoon with Schuller and pianist-musicologist Robert Levin.

On November 19 and 22, Levine and the BSO will perform Schuller's 1958 Spectra as part of their regular subscription season.

Schuller is frequently cited as the founder of the "third stream" movement, which combined jazz and classical music. Trained as a hornist, he played with the Metropolitan Opera Orchestra and Cincinnati Symphony before his 20th birthday. Later, he appeared with such jazz musicians as Dizzy Gillespie, Miles Davis, and John Lewis. His many compositions include the Pulitzer Prize-winning Of Reminiscences and Reflections (1993).
