"Bumpin' on Sunset" is the follow-up work to the previous year's "Bumpin'" with an added menace to the street. The harshness is reflected in blues that is very harsh sounding yet couched in the softness of the night. Claus Ogerman expertly paints the after hours feel with a very lean arrangement, letting Montgomery be the focus of this work. Ron Carter is on bass, Ray Barretto is on congas and Grady Tate is on drums on this March 1966 date.
