Just curious how you crossed paths with this album (I know nothing about it, and  thinking you at least paid $25 and want to recoop your investment). 

Yes, the timing basically matches the CD running time.  This one is not for the faint of heart.

I think this seems to be an upload of the entire CD — at least what comes up searching on YouTube for… 高柳昌行 ・ 阿部薫 – 解体的交感  

Recorded live At Kousei Nenkin Hall, Tokyo, June 28, 1970. First CD edition. This first pressing was a limited edition in mini-LP style sleeves. Subsequent pressings came in a regular jewelcase. Note that the entire CD and case writing is in Japanese, I had to use google translate to figure out what I had.  And the music is even more lost on me, just totally not my thing, so I'd like to find a good home for this. https://www.discogs.com/release/1113938-高柳昌行-阿部薫-解体的交感 $25 shipped in USA or best offer or interesting trade.   PM if interested.

That's a pretty good price for that set.  People have been asking absurd prices for it for years. Like $999.   $100 per disk?  I don't think so. There don't seem to be many for sale. I have some files I found so I've heard it but have been looking around for a reasonably priced copy for years.  My concept of a 'good price' for a Mosaic is somewhere close to the original price, which was maybe $15/disk years back and is now more like $18.  And the market is such that I have often snagged used sets for something in that neighborhood or less.  Recently I got the Buddy Rich set for $35 including shipping!  That one's got to be a record low price for me. A 'reasonable price' for me on a set that is rarer or generally fetches higher prices would be about $20-$22 per disk. Some stay stubbornly high, like the Ferguson.  I don't think I have ever seen one as low as the price you got.
