Pink Floyd were one of the first British psychedelia groups, and are credited with influencing genres such as progressive rock and ambient music. Four albums topped US or UK record charts. The band were inducted into the US Rock and Roll Hall of Fame in 1996 and the UK Music Hall of Fame in 2005. By 2013, they had sold more than 250 million records worldwide, with The Dark Side of the Moon and The Wall two of the best-selling albums of all time.
