"What makes Trombone Champ special, other than being the first of its kind, is the fact that, unlike most other music games, it gives players the freedom to play any note at any time - meaning you're not just playing along with the music, you're playing it, resulting in some hilarious renditions of very famous songs."
Check out the introduction video (approved by the International Association of Trombones and Baboons) for Trombone Champ at Steam.
