Bought this for my teenager at the recommendation of his percussion teacher. The kid has lots of band/orchestra percussion experience but just got a drumset. He's been very enthusiastic about working through the grooves, reading the book's explanation for each, watching the video demo of technique, then practicing with the playalong tracks. Apparently the playalong tracks are a lot of fun, because he often picks them over video games.There's a code in the book that he used to download the audio to his phone, more convenient than playing them off the DVD. One suggestion for players who wear earplugs or muffs: You'll want a pair of isolation headphones to hear the audio at reasonable volume over the drums.
