One story that circulated on Agon was that Grant Green would come to Blue Note with his 'substandard' junky music wanting them to record it. Grant Green didn't make substandard music even before he became a professional, and was just playing for the joy of playing and being heard.
I let the circulater know what I thought about him. He might just crawl out from under his rock and be heard since he knows I'm talking about him.
