Agustin Perez of Mule Walk & Jazz Talk compiles some amazing comments about jazz from the 1920s. Including Virgil Thomson:
Jazz rhythms shakes but it won't flow. There is no climax. It never gets anywhere emotionally. In the symphony it would either lose its character or wreck the structure. It is exactly analogous to the hoochee-coochee"
It only gets better from there. [Mule Walk & Jazz Talk: Early jazz commentators in the 1920s: some gems]
