This Classical Roundup has a decidedly American bent: Leonard Bernstein and Hilary Hahn bring life to Ives, Mikhail Simonyan plays Barber, and Leonard Pennario rolls though Gottschalk. To round things out, and for a touch of international diversity, Matt Haimovitz takes on Arcade Fire (they're Canadian!) and The Anonymous 4 offer law-breaking 13th-century French songs. All that and more are waiting below. Enjoy.
