On Monday, Nov. 21, the MIT community will have a rare opportunity to see and hear Pulitzer Prize-winning composer, conductor, teacher and scholar Gunther Schuller -- and wish him a happy birthday. Students, faculty and staff are invited to attend a free rehearsal of the MIT Wind Ensemble (MITWE) in preparation for the group's Dec. 2 concert celebrating Schuller's life, achievements and 80th birthday (Nov. 22). Schuller's "Blue Dawn Into White Heat," his 1955 arrangement of "Blue Moon," and Scott Joplin ragtime works are among the pieces on tap for the rehearsal and concert. Schuller will also speak. "[Schuller] always has a lot to say ... about the music, and how we are playing it," said MITWE conductor Frederick Harris. To attend, e-mail firstname.lastname@example.org.
