Holy music

Churches are known for having great acoustics, and this Saturday and Sunday, the Sacramento chamber choir Sacramento Master Singers takes advantage of the acoustics at the First United Methodist Church with a program called Mass2 (Mass Squared). The Master Singers were established in 1982 and are directed by Dr. Ralph Hughes. At this concert, the group will perform Ola Gjeilo's Sunrise Mass for choir and string orchestra, excerpts from Frank Martin's Mass for Double Choir, and spirituals such as Moses Hogan's “Elijah Rock” and Hall Johnson's “Ain't Got Time to Die.” Both shows are a tribute to Sacramento choir and orchestra director (Camellia Orchestra, River City Chorale, American River College) Walter Kerfoot , who will be in attendance on Sunday. $20, 8 p.m. on Saturday, March 15; and 3 p.m. on Sunday, March 16; at First United Methodist Church, 2100 J Street; (916) 788-7464; www.mastersingers.org.
