It's a quintet session from 1962 with Evans, Zoot Sims, Jim Hall, Ron Carter, and Philly Joe Jones. It was first issued as a Japanese LP. It's been issued in the U.S. on CD as Loose Blues.
Oh, that's a nice sleeve! I never saw that one before. Same artist who did 'Matador'.

The actual cover is a somewhat lighter shade of green than the color in the image I posted.
I figured it was that stuff. Thanks.
