Dave Beck speaks with guest conductor Masaaki Suzuki. Together with his son, Masato Suzuki, Masaaki has created a performing version of Mozart’s very last composition, the famously unfinished Requiem Mass. The piece was written by Mozart on his deathbed and it was left to his students and others to complete the work. Masaaki Suzuki leads the SSO, Seattle Symphony Chorale and vocal soloists in Benaroya Hall this week in an edition of the Requiem that the Suzukis put together from fragments of the music Mozart left behind. All three of the works on the program this week explore topics of mourning and loss. There are also works by Toru Takemitsu and Karl Amadeus Hartmann on the program.
