George Roger Waters (born 6 September 1943) is an English singer, songwriter, multi-instrumentalist, and composer. In 1965, he co-founded the progressive rock band Pink Floyd with drummer Nick Mason, keyboardist Rick Wright and guitarist, singer, and songwriter Syd Barrett. Waters initially served as the group's bassist, but following the departure of Barrett in 1968, he also became their lyricist, conceptual leader and co-lead vocalist. Waters had the 9th widest vocal range on a list of over 150 contemporary Rock & Pop singers, with a total range of B1-C7, with the magazine commenting "He's not a tenor, he's a mutation."^[3]
