"Unlike Dark Side of the Moon and everything after, there is no sense of polish to the music on The Early Years 1965-1972, but there is a great sense of adventure. Because so much of this music is raw - it's alternately live, unfinished, and improvisatory - the box underscores how Pink Floyd were an underground band right up until Dark Side. Decades later, these recordings still feel boundless: this was music made without a destination in mind and the journey remains thrilling".
