Pink Floyd's second album, originally released in 1968, was the first album to feature David Gilmour, who replaced Syd Barrett on guitar and vocals. It is both the last Pink Floyd album on which Syd Barrett appeared and the only studio album to which all five band members contributed. This is Pink Floyd in transition from Barrett's psychedelic whimsy to the style of their epic pieces. Classic tracks include 'Jugband Blues' and 'Set The Controls For The Heart Of The Sun'.
