The Kronos Quartet has a long history of performing music with a political edge. Music for Change: The Banned Countries, coming up Saturday at Stanford’s Bing Concert Hall, is no exception. After the Trump administration issued executive orders limiting travel from majority-Muslim countries last year, the director of Stanford’s Iranian Studies program, Abbas Milani, was upset. "It's shameful on a human basis. But it's also destructive to the fabric of culture in this country. And, I would submit, to the long-term strategic interest of this country," Milani says.
