It’s 1967 and The Pink Floyd have followed their increasingly deranged leader Syd Barrett to the very Gates of Dawn where some genuinely weird shit is going down. But don’t ask him exactly what. He’s too deep into the psychedelics to communicate on a rational verbal level, and he just keeps going deeper and deeper. Yet this particular message speaks volumes anyway. It calls itself Pow R Toc H and, in spite of the genuinely tragic madness that informs it, it’s really quite fun in a harrowing way.
