Following his legal and philosophical split with Pink Floyd in 1986, Waters began a solo career, releasing three studio albums, "The Pros and Cons of Hitchhiking" (1984), "Radio K.A.O.S." (1987), and in 1992, the highly acclaimed "Amused to Death". In 1990, Roger staged one of the largest rock concerts ever, "The Wall Concert in Berlin", on the vacant terrain between Potsdamer Platz and the Brandenburg Gate. In 2005 he released the critically acclaimed opera, "Ça Ira", which would go on to top the classical charts in America and Britain, as well as joining Nick Mason, Richard Wright and David Gilmour, for an historical performance at the 2 July 2005 Live 8 concert in London's Hyde Park, Pink Floyd's first public performance with Roger in 24 years.
