After performing at a night dedicated to Ed Blackwell and Don Cherry, vibraphone legend Karl Berger invited trumpeter Knuffke to Woodstock to teach and perform with him, from which this lovely album of duets was born, 2 CDs of original compositions of free and lyrical playing. "Karl and I met when we shared the bill for an "Arts for Art" night of music dedicated to Ed Blackwell. Karl was a longtime associate of Ed's. There were two duets featured that night. Karl played duo with the great William Parker and I was invited by drummer Gerald Cleaver to play duets from the record "El Corazon" and other tunes in tribute to Ed Blackwell and Don Cherry. Karl of course played a tone with Don too! After this meeting Karl and I became fast friends. Karl invited me to teach with him at the Creative Music Studio in Woodstock, NY, and now I have 2 times. It was there that we played duo for the nightly Guiding Artist concert and the concept of this album was born. Playing with Karl is so free and natural. It is my sincere pleasure to have him as a friend and a musical brother."-Kirk Knuffke, from the liner notes.
