Cadentia Nova Danica's 1966 concert is a wonderful gem, and - finally - no longer a hidden one! These live recordings from the 1960s, made at the legendary Jazzhus Montmartre, showcase a futuristic avant-garde jazz. This is John Tchicai's group, formed after his return from New York, and highlights the freedom that the saxophonist gave his young colleagues, encouraging them to explore the boundaries between composition and improvisation.
