CANTUS
Opening Thursday: With "When Twilight Falls," Cantus takes a romantic view of the time when daytime transforms to night, a time that is beginning and ending, through the nine-guy ensemble's trademark mix of sacred, classical and folk music. A highlight is the premiere of "A Source of Light" by Arab-American composer Mohammed Fairouz, setting texts by the unlikely bedfellows of Isaac Newton and 20th-century American poet Charles Bukowski. Also featured is the U.S. premiere of "A Song of Sky and Sea" by Cantus' own Paul Rudoi. (7:30 p.m. Thu., Cowles Center, 528 Hennepin Av.
