It's a Blue Note Groove Thing - I'd say defined by Higgins drumming (starting with HH's WM Man - before Sidewinder), except that Blue Mitchell's "High Heeled Sneakers" (w/A; Foster) and Donald Byrd's ____________ (w/Freddie Waits) fit into that bag, whatever you call it. Lou D w/ Egregious Muhamed, that's a whole different thing, groovey in it's own right.
