Tune in Tuesday at 7PM as MacArthur "Genius" violinist Leila Josefowicz premieres a new work by Stephen Mackey written in memory of his mother, and Gustavo Dudamel conducts the LA Philharmonic and Master Chorale in the profoundly beautiful "German Requiem" of Johannes Brahms. At the core of this masterpiece is a movement Brahms added in memory of his own mother; it is sung by Christine Schaeffer (Matthias Goerne is the male soloist).
