LOS ANGELES -- An $8 million production based on Pink Floyd's best-selling concept album, "The Wall," will be staged next week at the Berlin Wall.

The performance, set for July 21 at Potsdamer Platz near the site of the Brandenburg Gate, will feature the construction and demolition of an 80-foot-tall, 600-foot-long wall.

The concert will launch a five-year campaign to raise $800 million for the Memorial Fund for Disaster Relief, said founding member Roger Waters, who left the band in 1983.

"I want Russians, Germans, Americans building the wall and tearing it down, as a symbolic act of collaboration and the aims of the Memorial Fund," Waters said by telephone from London.

Waters said he wants to get "the armed forces freed to do disaster relief work when they have time off from training or polishing their boots."

The album, a story of a troubled rock star, came out in 1979 and sold some 19 million copies worldwide. A film version was released in 1982.

Due to join Waters on stage in Berlin are Sinead O'Connor, Van Morrison, Thomas Dolby, the Band, Bryan Adams, the Scorpions, the East Berlin Rundfunk Symphony Orchestra and the East Berlin Radio Choir.
