The 1970 section of the mammoth 2016 rarities clearinghouse The Early Years 1965-1972.
Hughesy's assessment: Sure, three takes on Atom Heart Mother might seem over the top to the non-Floyd enthusiast, the radio content is dominated by familiar material, and the soundtrack works better with something on the screen, But this is the Floyd evolving on their way to later, greater, commercial achievements, and is the sound of one of the great bands at (almost) the peak of their powers. Worthwhile.
