Celtic Woman brings its 20th Anniversary Tour to Chevalier Theatre. Celtic Woman is composed of four young Irish women whose performing skills bring centuries of musical and cultural tradition to life. In concert, their angelic voices and instrumental virtuosity are accompanied by a robust ensemble that includes Irish dancers, bagpipers, and a full band playing an array of traditional Celtic instruments, including bodhrán, tin whistle, bouzouki and Uilleann pipes. The group’s repertoire encompasses Irish classics, contemporary songs, classical favorites and stirring originals. Tickets are $47 to $147 through the Chevalier Theatre website/Ticketmaster. To avoid online ordering fees, purchase tickets at the Chevalier Theatre Box Office, which is open on Fridays and Saturdays from noon to 6 p.m., as well as two hours before every Chevalier Theatre show.
