When I was in college in the 70’s, I took an Introduction to Jazz course. One requirement was choose a jazz musician and give a presentation about them in class. I owned no jazz records.
So I went to Korvette’s at the mall and looked for jazz records in the 25 cent cut out bin. Point of Departure was in there. I had no idea who Andrew Hill was. But one listen and I went to the regular record store and happily paid full price for anything I could find by Hill.
