“For the year leading up to the 100th anniversary of its first concert on Oct. 24, 1919, the [Los Angeles Philharmonic] has hired Frank Gehry to design a permanent home for music director Gustavo Dudamel’s YOLA youth education project. The L.A. Phil also will premiere an unheard-of 50 new works that it has commissioned. It will reach out to community groups to distribute 10,000 free tickets to concerts and events, and it will partner with dozens of local and international arts organizations, from the organizers of Hollywood’s Academy Awards to London’s Royal Ballet.
