This was accomplished by the two "marathon" sessions of May 11 and October 26, 1956 that gave birth to four separate LPs: Cookin'; Relaxin'; Workin'; and Steamin'. October 26, 1955 was the date of the first quintet recording for Columbia. Material from that session was mixed with two subsequent dates for the label (June 5 and September 10, 1956) to comprise 'Round About Midnight which Columbia released in 1957, after Davis's Prestige contract had officially expired.

They don't need to be looking at me
