Plays Ellington was from '65 - it's a favorite of my Dad's. McCoy's touch seemed pretty tough and insistent on the Blakey date you mention; it's a Bu LP that I return to fairly often.
He's a furious player, sure, but at his best not without lyricism. I do know what you mean about the "chunkier" style as a post-Coltrane thing, but I imagine its gestation was a long time coming.
