The above message was displayed above the stage of musician Roger Waters’ “Us + Them 2018” concert in Berlin, Germany on June 2.

Roger Waters was part of the iconic rock band Pink Floyd from 1965 to 1985. For the past 33 years, he has continued a solo career, which has included staging the largest live concert event in history.

Throughout his long career, singer-songwriter Waters has spoken out publicly against war, oppression and injustice.

He emailed the World Socialist Web Site last month to convey his support for international action to defend Julian Assange.
