Afghan Youth Orchestra brings message of hope on two-week U.S. tour

The lulling sound of the sarod is loved by many, but the fretless instrument is difficult to master. That Negin Khpolwak's fingers are tough enough to press the strings is, in itself, a musical feat. But the sound of her sarod is all the more powerful because Khpolwak is an orphan, only 16, born the same year that the Taliban took control of her native Kabul, the same year it pummeled pianos with grenades and chopped off the hands of men who dared to strum sitars.
