Yep, I saw him that era too and the loudness level was significantly lower. Used brushes a fair bit, as I recall and more emphasis on standards compared with the earlier group. The playing in the early 80s was quite similar to that heard on ‘The Prime Element’ twofer.
Yep, saw Blakey at least 3 times 1980-83 and he was loud too, I agree. By then he must have been pretty well deaf.
