The Tenet Vocal Artists present “Double Take: Baroque Expressions From Italy & England.” Acclaimed early music ensemble TENET Vocal Artists share deeply expressive music from Claudio Monteverdi’s Italy and Henry Purcell’s England. Among the ensemble’s specialties, TENET explores the rich and fruitful way Baroque composers crafted duets as a way to double the impact of a single idea through the use of two voices with powerful and dazzling results.
