Roger Waters of Pink Floyd told the Guardian,

“I want the music industry to support Palestinians’ rights and
oppose this inhumane barrier …

“I was contracted to perform in Tel Aviv. Palestinians from a
movement advocating an academic and cultural boycott of Israel urged
me to reconsider. I had already spoken out against the wall, but I
was unsure whether a cultural boycott was the right way to go.

“The Palestinian advocates of a boycott asked that I visit the
occupied Palestinian territory to see the wall for myself before
I made up my mind. I agreed.

“Under the protection of the United Nations I visited Jerusalem
and Bethlehem. Nothing could have prepared me for what I saw that day.
The wall is an appalling edifice to behold. It is policed by young Israeli
soldiers who treated me, a casual observer from another world, with
disdainful aggression.”
