BlockflötenBox Band is a beautifully and modern method for recorder written by Daniel and Jeannette Hellbach. The method is divided into four volumes and each volume is accompanied by two CDs with recordings and accompaniments of studies and songs . 
Each volume can also be accompanied by a separate book with piano accompaniments. 
The school is written in German, but there is very little text. All the exercises and songs are presented in a very simple, clear and illustrative way.
