A video of Thelonious Monk's quartet playing "Rhythm A Ning". Essential viewing if, like me, you've never actually seen the man play.

Charlie Rouse - surprisingly immobile as he plays this dancing music, eyes closed.

The master - oddly plucking the the joyous line with both hands.

The drummer - (Ben Riley?) awesomely sober technique: minimal movement, but his ride cymbal settles like fairy dust when he comes back in in the middle of the bass solo.

A great performance, even if (or perhaps, even more impressive because) it is clear that they churned out this level of music night after night.
