I tend to agree with Peter, though there are some good moments on the Capitols; when I saw Cannonball, must have been early 1970s, I had been listening to his stuff with Miles and the Riversides, and his appearance was a big disappointment. Too much bad funky music of the kind that jazz musicians were trying back in those days in desperation at rock and roll's hegemony. We were hoping he would just PLAY, but everything fell into a monotonous groove. I've slways tried to avoid this kind of jazz, as jazz musicians don't do it half as well as people like James Brown - I don't begrude him his financial success at it, more power to him; it's just if you had to sit and listen to it, that was another story -
as for Pepper/Coltrane, a different problem - very few musicians of Pepper's generation truly understood Coltrane and post-Coltrane styles. Pepper thought if he broke a few notes, or overblew, he was being hip to the sound; unfrotunately not true. Same with Frank Morgan, who plays great bebop but than flails around aimlessly on Wayne Shorter tunes. I've even heard Jackie Mclean trying not-too-successfully to play "outside," and just fall back on endless cycles of fifths. This is not to say that some have not done it successfully (Bill Dearango is a great example), but mannerisms by themselves don't capture the style, just as a jazz musician endlessly repeating a flat third don't make funk (witness OP) -
