"In terms of introducing children to improvised music, Kramer's Harry Potter Jazz has a spark of brilliance and a quality of craftsmanship found in something like a Bernstein's narration of Prokofieff's Peter and the Wolf . . . in this case there is no narration, because none is needed. There are going to be tons of kids wanting to play music after hearing this. This is a great thing. " Roy Folcroft, the Smithsonian Ledger
"Finally something of Harry Potter people can hum. . . . "John Davis, CD journal
"This is very sophisticated jazz masquerading as a children's CD. It should appeal to children of all ages. " Anthony Ratcliff, The Times.
"Abracadabra. Williams is there in most of his glory, but somehow brought into focus by a nimble fingered, emotional and highly musical Mark Kramer. Fly over on a magic carpet and get it." Bradley Thompson, Stage and screen reviews.
