Interesting historical fiction!
Based on sources and well-sourced in the end notes, Greenwood puts this into a basic narrative on the advent of the Caribbean metal drum. This was an interesting slice of history to capture in the short form of the picturebook. There was a lot of potential for the informational that Greenwood missed, but he favored the context in which the drum became important so it was a decent call.
Lessac's illustrations are faithful to the Caribbean folk art tradition and have a vibrance that shows she gets the spirit of it. The best of her art reminds me of Gaugin or some later Van Gogh in the way it emphasizes color+light at the expense of light+shadow.
