Piano and straight up 4/4 drums:
Here we have an interesting chord progression idea. In the 4/4 groove, the piano plays the second chord on the "and" of 2... Very cool. The pickup for the second chord starts on two, as I visualized in the midi roll diagram.
With a root of C (what I played it in), this could be called C minor to D flat, major 7, while at the end of the fourth bar the progression finishes on G7.
