Boycott

"Many artists come under pressure to leave Israel off their tours. Some resist, like Paul McCartney. Others, such as Leonard Cohen, gave a significant part of the proceeds to the Parents Circle, a peace group of bereaved Palestinian and Israeli parents. The boycott campaign did, however, succeed in scuppering Cohen's plans to perform in Ramallah. Roger Waters came despite
pressure but made his own statement by moving the concert location from Tel-Aviv to Neve Shalom/Wahat al Salam, a joint Arab-Jewish community." (thanks David)
