A smart work by this young French illustrator who's really used the expandable nature of the accordion format to its full effect in telling this story. The story consists of a conductor reveling in the natural world, and with his baton he weaves a silent adventure with flying bird & plant-like creatures that fill out the symphony he's creating with nature's creatures. At the end of the book he comes down from his perch and plants his baton in the earth, and it begins to grow into a new plant.
The first edition of this book was published as an accordion in 2010, then republished in 2011, and finally published as a book in 2013. Each of the different language versions have used different names as well, from Applaus, to Diaposon (burst of sound: Fr.) and The Conductor (Eng. ed.). Here's a link to a fun video featuring this accordion book: Applaus (Buchtrailer mixtvision Verlag) - YouTube
