amazing album..still sounds fresh 40 years later.. I do still prefer the A-side but its interesting that so many musicians were more influenced by the instrumental more ambient B-side....One you hardly ever see in the shops.. I think in the US it sold less than 100,000 copies..I think the cover art is from a still from the movie The Man Who Fell to Earth.. I have a cheap paperback book of the movie which has the same cover..
