Chick Corea put it best: "Every drummer wants to play like Gadd because he plays perfect ... He has brought orchestral and compositional thinking to the drum kit while at the same time having a great imagination and a great ability to swing." Listen particularly to Gadd's great playing on the title tracks to Corea's The Leprechaun and Steely Dan's Aja, not to mention Paul Simon's "50 Ways To Leave Your Lover."
In this video, Gadd is playing Chick Corea's "Spain" with Al Jarreau's band. Check out his solo in the middle of the song. Amazing.
