George Roger Waters is an English rock musician; singer, guitarist, bassist, songwriter, and composer. He is best known for his 1965-1985 career with the band Pink Floyd as their main songwriter (after the departure of Syd Barrett), bass player and one of their vocalists. He was also the mastermind behind the majority of the band's songs, concept albums and many of Pink Floyd's symbols including the Pink Floyd Pigs and the marching hammers.
Following this, he began a moderately successful solo career releasing three studio albums and staging one of the largest concerts ever, The Wall Concert in Berlin in 1990. In 2005, he released an opera, Ca Ira and rejoined Pink Floyd at the Live 8 concert in London, on July 2, for their first public performance together in 24 years.
