Query: Piano, bass and ... guitar

Recorded at famous Hollywood jazz venue in 1955, this two-disc live performance captures the lyricism of cool jazz that typified the post-war scene. No drumming here. Herb Ellis keeps the the beat on guitar with Ray Brown on bass and Oscar at the piano.Oscar selected 30 tunes over several sets for 2.5 hours of thoroughly enjoyable music. Mostly standards with a few original compositions added. Most renditions are upbeat and lilting, with Oscar providing his signature sub-vocals.
