VoXX: Voice of Twenty is presenting its “Music of the Spirit” concert in five very different concert spaces, each chosen for its fine acoustics. The tour begins July 1 at Beechnut, the 100-year-old stone hut atop Beech Hill in Rockport (see story linked below).

The series continues Friday, July 6, at 7:30 p.m. at Rockport’s Union Hall, 24 Central St.; Saturday, July 7, at 7:30 p.m. at the Belfast Armory, Route 1; and Sunday, July 8, at 2 p.m. at the Old South Cushing Church on Salt Pond Road. The tour will conclude Friday, July 13, at 7:30 p.m. at Lewiston’s Basilica of Saints Peter & Paul.

The “Spirit” theme will be developed through a pair of polyphonic, 16th-century pieces: Palestrina’s “Veni Creator Spiritus (Come Holy Spirit)”; and the five-part “Dum Complerentur dies Pentecostes (When the day of Pentecost was fully come)” by Tomas Luis de Victoria. The performance of early works is a staple of the VoXX repertoire; others in this concert include William Byrd’s Miserere Mei, Deus and the Kyrie from Tomas Luis de Victoria’s Missa pro Defunctis.

As the group journeys through the ages, early works will be contrasted with more contemporary pieces. The singers will pair a 16th-century setting of “O Sacrum Convivium (O Sacred Banquet)” by Thomas Tallis with an aurally challenging version by the 20th-century French composer Olivier Messiaen. The haunting part-song “Rest,” a setting by Ralph Vaughan Williams of a poem by Christina Rossetti, and a lovely version of Ave Maris Stella by living composer James Macmillan will round out the contemporary offerings. The newest piece on the program will be Magnificat, composed in 2018 by Music Director John Mehrmann.

In a departure from its usual repertoire and language skill-set, VoXX will present a set of three short pieces sung in Old Church Slavonic: “Otche Nash (the Lord’s Prayer)” set by Stravinsky; and two versions of “Bogoroditse Devo (Ave Maria),” one by Stravinsky and the other by Rachmaninoff.

Some pieces are performed in smaller configurations. For this series, the men will perform Ave Maria Mater Dei by William Cornysh and the women will sing Gustav Holst’s Ave Maria. A mixed ensemble setting of the majestic Lux Aeterna by Sir Edward Elgar (an arrangement of the well-known Nimrod Variation) will round out the small ensemble selections.

Admission at the door is $15 (cash/check). For more information, visit voiceoftwenty.com.
