The Island Community Chorus will feature two great works from the 20th century choral repertoire in its annual spring concert, performed at 7:30 p.m. this Saturday, April 4, and again at 3 p.m. on Sunday, April 5, at the Old Whaling Church in Edgartown.

Under the direction of Peter Boak and with accompanist Garrett Brown at the piano, the chorus will present Leonard Bernstein’s Chichester Psalms (1965) and Carl Orff’s Carmina Burana (1937), as well as selections from the Liebeslieder Waltzes, written by Johannes Brahms in 1868 and 1869.

The concert program will open with the Carmina Burana, which is by far the most famous piece by the composer Orff. First performed in Frankfurt in 1937, it is a massive piece filled with driving rhythms and an exultant hedonism, with its themes the fickleness of fortune, the coming of spring and the pleasures (and perils) of drinking, gluttony, gambling and lust.

The Liebeslieder Waltzes, written for four-hands piano and voices, are among the most cherished of the lighter works of Brahms. The Liebeslieder, which will be sung in English by the Island Chorus, are love songs in which the choir and piano parts stand as equal musical partners. Together, these short waltzes are sunny, emotionally uncomplicated outpourings of the Viennese spirit.

The Chichester Psalms, a 20-minute piece which will conclude this weekend’s concert program, was composed by Leonard Bernstein in the spring of 1965 for a festival featuring the combined cathedral choirs of Winchester, Salisbury, and Chichester, England.

Each of its three movements includes a full text from the Book of Psalms. Perhaps the most remarkable is the second, in which the women’s voices open with an ethereally serene 23rd Psalm (“The Lord is my shepherd”), and are interrupted by an angry outburst from the men, who sing from Psalm 2, “He that sitteth in the heavens shall laugh!” When he combines these two themes at the end of the movement, Bernstein gives to the women one of the most remarkable sets of directions in the choral literature: They should sing above the men, he writes, as if “blissfully unaware of threat.”

For this weekend’s concerts, the Island Chorus has engaged Wesley Brown as the second pianist for the Liebeslieder, as well as harpist Sandra Bittermann and percussionist Brian Weiland. Hannah Marlin and Glenn Carpenter are soloists. All are welcome; a donation of $15 will be requested at the door.
