jazz drumming (detail)

One little effect I love is when the drummer doubles the tempo, but just on the high-hat, so that the original tempo is maintained on the ride and the high-hat is playing on every off-beat. The net effect is exciting, then destabilising: there's the initial double-time illusion, then the "wait a minute..." elucidation. Old stuff (Max Roach did it and probably others before him), I know, but still nice when it comes up on, say "A Handful of Stars," the first track on Serge Chaloff's "Blue Serge" (which is, as you might have guessed, the example currently in my ears).
