Border CrosSing, led by artistic director Ahmed Anzaldúa, joins the Minnesota Orchestra with El Mesías, a bilingual Spanish-English cross-cultural combination of George Frideric Handel’s Messiah and Navidad Nuestra, a Christmas cantata by Argentinian composer Ariel Ramírez. Together with the vocal soloists and choir, the unique combination of Andean instruments and the Baroque orchestra blur the lines between Western classical and South American folk traditions.
