Music adds color to a black-and-white world, and that color spreads as we carry the music with us into the world. Perhaps it's a big topic for a small picture book, but WOW is this book awesome!
The simple art is amazingly rich with details, and the swirling pointillist color of the music employs all the senses in the audience's aural enjoyment. Don't I sound like an art critic? :)
Trust me. Genius!
