Ars Gratia Populi (Latin for “art for the people’s sake”) is a vocal ensemble that explores the interplay between art music and folk music in an a cappella setting. The six unaccompanied voices of the ensemble bring purity and intricacy to everything from Renaissance madrigals to Scottish Gaelic ballads to maybe even some modern standards. Tickets $10.00, $7.00 for students and seniors Purchase tickets at www.mcleancenter.org
