Be carefull of some of his recordings that were"never released" and they just found the long lost tapes and are issueing the recordings. Grant Green had a habit,used to show up @ the studio needing a fix and would lay down some tracks and then disapear. Alfred Lion's stated that is why there is so much stuff that is released after they say they lost the tapes. Some of it is inferior,until Lion's got smart he would front the artist his pay only to have them return all high on smack and the material was sub standard and wasn't worth releasing. Sometimes because Blue Note operated mostly lacking finances an artist would record something very good but the trend for that type of music wasn't selling or the artist's material wasn't selling so it was canned only to be released later. An example of this was Back to the Tracks by Tina Brooks which although the album jacket was shown on Blue Note album inserts was never released. It was later released on Japanese Blue Note if you bought all twelve of their vinyl re issues in the mid 80's. Each reissue had a ticket and if you sent all 12 in you were sent Back to the Tracks. It was then included in a Tina Brooks Mosiac box set and now is available on CD.
