The Rhythm Section is that of the Miles Davis quintet. The section of Red Garland (p), Paul Chambers (b), and Philly Joe (d). I like the knowingness of the title! Art is fluent and meshes well with this section. They play Dizzy's "Tin Tin Deo," some standards and some straight-ahead blues.
All my albums have been clustering in the late 50s and early 60s so far.
