The a cappella choirs at American Fork and Mountain View high schools will combine for two concerts in "A Tribute to John Rutter."

The first concert - sponsored by the Utah Valley Choral Society - is 8 p.m. March 31 in the Provo Tabernacle. Admission is $2.The second concert, in Salt Lake City, is part of the Temple Square Concert Series. It will be performed free at 7:30 p.m. April 4 in the Assembly Hall.

The American Fork A Cappella Choir, directed by Lois J. Johnson, is the largest of five choirs at the school. The 105 members will perform as part of the 250-voice chorus at the National Choral Festival at BYU this spring. In 1988, the choir received the Gold Award and first place in the large concert choir division of the Heritage Festivals at Knott's Berry Farm.

The Mountain View A Cappella Choir, a select choir of 100 voices, is directed by Brian Petersen. The choir has performed in many regional, state and national settings during its nine-year history.

It received top honors in the Southern California Vocal Association Choral Festival in Thousand Oaks in 1988. This choir will also sing in the national festival at BYU.

The program will begin with the combined choirs singing four Rutter arrangements of hymns, followed by the Mountain View Chamber Choir's rendition of Rutter's "Five Childhood Lyrics." The American Fork Chamber Singers will perform his "Three American Lyrics." The a capella choirs will also perform separately before combining for Rutter's "Gloria," which will feature brass, percussion and organ accompaniment.

Johnson, who also directs the Utah Valley Choral Society, said the joint high school concert is the fruition of years of planning. "I hope it will become an annual thing to highlight a couple of local high school choirs in a concert," she said. "We plan to make it part of our regular season."
