Lifting Their Voices: The Gay Men’s Chorus of Los Angeles has announced the program for its concerts in March and April. The 165-member chorus, under the artistic direction of Jon Bailey, will perform the newly commissioned “Hidden Legacies” by L.A.- based composer Roger Bourland. The work chronicles the gay community’s experience with AIDS. The group also will perform the local premiere of John Adams’ “KTAADN” at its concerts on March 29 at Royce Hall, UCLA; April 11 at the Wiltern Theatre; and April 12 at Pomona College.
