Jack Dejohnette playing a straight 8th groove on Freddie Hubbard’s Polar AC. This gets called an ECM feel today, but maybe we should start calling it a CTI feel. Change it up, direct people to some other records.
I’ve transcribed the intro of the tune, right up until the trumpet comes in:
The groove suggests a 2/2 or half time feel— a free texture somewhere between a samba and funk feel. The main point of interest is the mostly-linear snare drum and bass drum activity, with some overlapping. The accents are subtle— he plays the snare drum at a pretty even volume.
