The piano duet Duo Amal includes two hugely talented young classical pianists who have been heralded as among the top pianists of their generation. BisharaHaroni and YaronKohlberg have toured the world, and Friday night, they’ll be sharing their artistry at the Gordon Center for the Performing Arts in Owings Mills. But as with most of their concerts, musical artistry won’t be the only thing they’ll be sharing. They’ll also be sharing hope. BisharaHaroni is Palestinian. YaronKohlberg is Israeli. With tensions in Israel and the occupied territories as high as they have been in years, and with talk of another Intifada, the fact that two artists from opposite sides of the conflict are choosing to perform together is noteworthy on its face. But as important as their collaboration may be as a symbol of hope for peace in the Middle East, let’s be clear: these guys can play.
