Founded in 1973 by director Peter Phillips, Tallis Scholars perform tonight at 7:30 at the Cleveland Museum of Art. Through their recordings and concert performances, they've become the leading exponents of Renaissance sacred music throughout the world. They'll play "War and Peace," a program commemorating those who lost their lives in World War I; the concert features works by Josquin, Guerrero, Pärt, Mouton, Lobo, Victoria, Tavener and Palestrina. Tickets start at $38. (Niesel)
