This week, we look ahead to a new exhibition at the Brandywine River Museum. Factory Work examines the relationship between Pop artist Andy Warhol and realist painter Jamie Wyeth and graffiti artist Jean-Michel Basquiat. Jason Peifer speaks with the composer of "Windy City," the first show of the Walnut Street Theater's new season; Susan Lewis looks back on two weeks accompanying the Philadelphia Orchestra on its recent tour of Europe's summer music festivals.
