Passage: In November 1989, the Berlin Wall fell, and in July 1990 Waters staged one of the largest and most elaborate rock concerts in history, The Wall – Live in Berlin, on the vacant terrain between Potsdamer Platz and the Brandenburg Gate. The show reported an official attendance of 200,000, though some estimates are as much as twice that, with approximately one billion television viewers. Leonard Cheshire asked him to do the concert to raise funds for charity. Waters' group of musicians included Joni Mitchell, Van Morrison, Cyndi Lauper, Bryan Adams, Scorpions, and Sinéad O'Connor. Waters also used an East German symphony orchestra and choir, a Soviet marching band, and a pair of helicopters from the U.S. 7th Airborne Command and Control Squadron. Designed by Mark Fisher, the Wall was 25 metres tall and 170 metres long and was built across the set. Scarfe's inflatable puppets were recreated on an enlarged scale, and although many rock icons received invitations to the show, Gilmour, Mason, and Wright, did not. Waters released a live double-album of the performance, which has been certified platinum by the RIAA.In 1990, Waters hired manager Mark Fenwick and left EMI for a worldwide deal with Columbia. He released his third studio album, Amused to Death, in 1992. The record is heavily influenced by the events of the Tiananmen Square protests of 1989 and the Gulf War, and a critique of the notion of war becoming the subject of entertainment, particularly on television. The title was derived from the book Amusing Ourselves to Death by Neil Postman. Patrick Leonard, who worked on A Momentary Lapse of Reason, co-produced the album. Jeff Beck played lead guitar on many of the album's tracks, which were recorded with a cast of musicians at ten different recording studios. It is Waters' most critically acclaimed solo recording, garnering comparison to his work with Pink Floyd. Waters described the record as, a "stunning piece of work", ranking the album with Dark Side of the Moon and The Wall as one of the best of his career. The album had one hit, the song "What God Wants, Pt. 1", which reached number 35 in the UK in September 1992 and number 5 on Billboard's Mainstream Rock Tracks chart in the US. Amused to Death was certified Silver by the British Phonographic Industry. Sales of Amused to Death topped out at around one million and there was no tour in support of the album. Waters would first perform material from it seven years later during his In the Flesh tour. In 1996, Waters was inducted into the US and UK Rock and Roll Halls of Fame as a member of Pink Floyd.
