This week, the San Francisco Symphony announced the retirement of Michael Tilson Thomas after 25 years as music director.
Tilson Thomas is best known for his championing of the works of the Austrian composer Gustav Mahler, including a series of Grammy Award-winning recordings.
But this is just one piece of the conductor’s contributions to classical music.
"His advocacy for American music and American composers is unparalleled," says California Symphony and Las Vegas Philharmonic music director Donato Cabrera. "He was a strong advocate for the iconoclasts of the American music scene like John Adams, Lou Harrison, and Charles Ives."
Cabrera worked closely with Tilson Thomas as the Symphony’s resident conductor for seven seasons. He says his boss was a brilliant mentor who shared personal stories in his dressing room with his protege.
"He would share a little memory of when he was working with Stravinsky, or having an evening of word games with Leonard Bernstein," Cabrera says.
Silicon Valley-based composer Mason Bates also benefited from Tilson Thomas’ mentorship. Bates worked with the conductor on several high-profile world premieres, including Mothership, a cutting edge collaboration with YouTube in 2010.
"He has an incredible ability to communicate complicated artistic ideas in the most engaging way, while not sacrificing substance at any level," Bates says.
Bates says Tilson Thomas made classical music matter to people at a time when its appeal is waning, like through his Keeping Score and MTT Files radio projects, and his mid-concert musings to the audience.
"When Michael speaks, what he says is interesting to everybody in the room whether it be a 30-year veteran of the San Francisco Symphony or a new audience member who's never even walked into Davies Hall," Bates says.
Tilson Thomas will step down in 2020 at 75 years old. He will continue to conduct the orchestra a few weeks a year and undertake special projects for the organization.
