Largest concert - performers

The largest single rock concert, in terms of participants and organisation, was Roger Waters' production of Pink Floyd's The Wall staged on July 21, 1990 in Potsdamer Platz, straddling East and West Berlin, Germany, when 600 people performed on stage and an estimated 200,000 others made up the production crew. 600 people performed on a stage measuring 168 m (551 ft) long and 25 m (82 ft) wide at its highest point. 200,000 people gathered for the building and demolition of a wall made of 2,500 styrofoam blocks symbolising the demise of the Berlin Wall.
