He is described as "...one of the strongest jazz pianists on the planet, an underrecognized giant" by Bruce Lee Gallanter - Downtown Music Gallery

Michael G. Nastos in the All Music Guide describes John Esposito as playing "...lucid, forward thinking, rhythmically propelling ideas...he succeeds on many real and important levels in creating some of the finest new modern jazz you may hear in the post Wynton Marsalis era...A bold conception and execution to be sure...from a brilliant player who deserves wider attention."

John Szwed in the Village Voice describes John's playing as having, "the lustrous clarity of a gamelan band using repetition so brilliantly that crystalline forms accrue from it."
