as a drummer, listening to the way tony plays at just 18 years of age is nothing short of breathtaking. the way those guys interact with each other is truly phenomenal. just listening to four & more, and the way they can communicate so damn well when playing insanely up-tempo stuff is inspiring. they've got such a unique bonding, where you'd think they were triplets, they just know so much about each other's playing and they're all so aware of going on.
have you seen the 'one night with blue note' 1985 reunion concert? the three great men play a great rendition of cantaloupe island. all still in great shape too!
