December 1975 was a busy month for Warne Marsh and Lee Konitz. It was Warne Marsh's first visit to Europe. They played December 3,4 & 5 at the Montmartre in Copenhagen and came back the 27th and played yet another concert at the Montmartre. They were at Rosenberg studio December 28 and 29 for further recordings. All dates were recorded and the result can be heard on this 4 CD box. It is amazing music from the two Lennie Tristano "pupils". They played with the Danish musicians Ole Kock Hansen (p) Niels-Henning rsted Pedersen (b) and Alex Riel (dr) and for the later sessions with Dave Cliff (g) Peter Ind (b) And Alan Lewitt (dr).
