“MTT25: An Online Tribute Event for Michael Tilson Thomas” will include a pre-recorded performance, pre-recorded guest tributes from the likes of Metallica’s Lars Ulrich and famed singer-songwriter Bonnie Raitt, and it will be hosted by Tony-Award winning singer-actress Audra McDonald and famed opera vocalist Susan Graham.

The hourlong performance, which will begin at 5 p.m., will take place on the day that would have been Michael Tilson Thomas’ final concert as music director of the orchestra, a scheduled performance of Mahler’s “Symphony No. 8, Symphony of a Thousand.”

Other guests that have pre-recorded tributes include cellist Yo-Yo Ma and opera vocalists Renée Fleming, Julia Bullock and Measha Brueggergosman. Other surprises were promised.
