Charlie Parker Played Be Bop by Chris Raschka
This book may be a bit of a stretch for some young people. There is no real story. It is, as the title suggests, based on be bop in its very format with lines like "overshoes overshoes overshoes o" and my favorite "never leave your cat alone". It's all about exploring rhythm and taking artistic risks. The illustrations are highly stylized, which works well with jazz text. I highly recommend reading this book with children of all ages, though I do recommend reading through it several times yourself, practicing your delivery.
As a side note, the PBS program Between the Lions devoted a rather excellent episode to Charlie Parker Played Be Bop if you're looking for some inspiration.
