In June 1955, in the Atlantic studio, standards provided the starting base for the long and wonderfully sophisticated improvisations by Lee Konitz and Wayne Marsh, who were at that time pupils of the great Chicago maestro Lenni Tristano. Although the numbers are declared as own compositions, such as "Background Music" and "Ronnie's Line", they are actually none other than adaptations of "All Of Me" or "That Old Feeling" - but at the very highest level. Lee Konitz always called this 'The Twelfth Step'.
