The European freejazz scene of the ‘60’s never really appealed to me. Don’t know why exactly but it just doesn’t. This whole topic makes me very much aware I know so little jazz from my own continent!
have to say that I do like the Polish Jazz Series. Komeda and Stanko of course but also Andrzej Trzaskowski and Zbiegniew Namyslowski. Great music by underestimated musicians. Also like The Ganelin Trio from the Soviet Union and Szabados from Hungary. But I believe that was just a decade later than what you are looking for.
