A panoply of puns! A manifestation of musical merriment! A fanfare of frivolous tomfoolery! Colby College Collegium will present Orazio Vecchi’s 1604 madrigal cycle Le veglie di Siena (Night Games of Siena), a work filled with witticisms, wordplay, and wholesome, wholehearted wizardry of all genres. Collegium will be joined by a quintet of early music professionals, including Shannon Canavin, critically acclaimed soprano and artistic director of Exultemus, one of Boston’s exclusive early music ensembles.
