Query: One of Music's Experimental Master Pieces

Finally!!I have been searching for years and years for a copy of this masterful work of art. Once a part of one of the largest private vinyl collections I knew about (mine), the entire collection was lost to a fire. I looked and looked and could only find that it was out of print.Now it is back. Not much can be found in this vain of music today. Everything must have a short catchy tune and emphasis on the short. It seems that todays music fans don't have long attention spans and do not listen to music for music's sake. Instead todays music is used to fill up sound voids or cover up other noises.There is much creativity to be found in this master piece and new surprises to be heard with every listening. If you love music and don't mind a bit of theatre to go with it, you'll love this work of art.
