The Music Exchange's liquidation sale continued in Kansas City for two weeks in October. I went on a day when a box of LPs went for $20. I was able to get about 80 LPs into the box, so I guess that is 25 cents each.
These included David Liebman's "Lookout Farm" and "Drum Ode", three volumes of Duke Ellington in the French RCA series, and many other worthy albums.
