From the recording Benedictus-Agnus Dei

Requiem
Composed in 1976, this setting of the Missa da Requiem represents the composer’s first foray into a larger scale form. The five movements in the piece are the Introitus, Kyrie, Sequentia, Benedictus-Agnus Dei and Lux Aeterna. The piece is scored for choir SATB, string orchestra with organ continuo, flute and harp, and was first performed at a UCLA Music Department concert with Roger Wagner conducting the A Capella Choir on May 10, 1977 at Schoenberg Hall on the UCLA campus. The piece was enthusiastically received with a standing ovation. The composer subsequently made revisions to the score and orchestration, and conducted the piece himself in concert with the Pierce College Premiere Chorale and San Fernando Valley Symphony in 1994.

Lyrics

Benedictus qui venit in nomine Domini.
Hosanna in excelsis.
Agnus Dei, qui tollis peccata mundi,
dona eis requiem sempiternam.
