From Tom Kelly’s MUSINGS column: We spend a lot of time studying instruments of the past for what they can tell us about music they were designed to play…but the voice is an instrument that can do almost anything. In early music, I think we tend to constrict it a lot.

William Byrd was influenced by Italian madrigals and sacred choral music as well as the colorful keyboard music from Venice. British keyboardist Freddie James puts the English composer in a lively dialogue with the Italian Renaissance, often with hair-raising results.

The canzon-mottetto, a 17th-c. Milanese genre, is a hybrid work that alternates, then combines, an a cappella motet with an instrumental canzona until it becomes a double-choir motet in which one choir sings, the other plays. The Breathtaking Collective and Cappella Mariana join for an inspired exploration of this delightful repertoire.

Apollo’s Fire, led by Jeannette Sorrell, has just released possibly the best available small-sized period-instrument recording of Bach’s B-minor Mass. This is thanks to their vision of Bach’s concept of the Mass as a whole with nothing amiss: correct choices of tempi, balances of orchestra, chorus, and solo voices.
