In the history of music there's one compilation that can be called the bible and this is the Harry Smith 1950's Anthology of American Folk Music compilation. Why is this the bible? because all the folk movement that came from the early 60s till today was influenced by this. But the only other compilation that could also be called "a bible" are these three volumes of Endless Journey. Chocolate Soup For Diabetics and The Pebbles and Nuggets could also be called Bibles for the genre. But in this series are the most incredible and sought after tracks made in the USA around the 60's and early 70's. The guys that made this series should be recognised as masters of THE INVISIBLE COLLEGE. This series helped in the early 80s to trace the map and help to fill the jigsaw that is psychedelic music. What else could we say? ............ THE BEST EVER COMPILATION SERIES ! If you don't know this one, then you need this. Each track is perfect. A piece of art.
