This is the Sam Lazar Trio playing "Space Flight Part 1" from a blue wax copy of small St. Louis label Cawthron, recorded in 1959.
The Trio consists of: Sam Lazar (org), Grant Green (eg), possibly Chauncey Williams or Phillip Wilson (dr)
Since what is everywhere described as Grant Green's first recording session (the one with Jimmy Forrest) took place in december 1959 and the Cawthron record was definitely pressed in 1959. It may well be that indeed this is Green's first recording date.
Note that this version is not identical to the one recorded for Argo in 1960 with a similar personnel.
