Former member of Pink Floyd, George Roger Waters left the group in 1985 noting creative differences and has been on a solid solo career ever since. In 1990, he held The Wall – Live in Berlin, believed to be one of the biggest rock concerts in history with upwards of two hundred thousand people in the audience. He also has multiple studio albums including The Pros and Cons of Hitchhiking, Amused to Death, and Radio K.A.O.S. Other than his rock music career, Roger Waters also released the opera Ça Ira based on his wife’s libretto on the early French Revolution. He is credited with the soundtrack of the movie When the Wind Blows released in 1986. The concert album Radio K.A.O.S was released a year later and featured a story about a mute boy only able to communicate through radio transmissions. His powerfully themed albums didn’t stop and in 1992 he released Amused to death, a satire of how war had become some twisted form of entertainment. In 2005, he joined Pink Floyd on stage at the Live 8 concert noted as the last time the original band would play together for their final performance. From 2006 to 2008, Waters played The Dark Side of the Moon, the Pink Floyd album, during his tours in its entirety. In September 2010 in the US, he is planned to run a tour of The Wall that will end June 2011 in Europe.
