I have been a fan of Key's work with their anime series and games. They created the AIR series, and their opening themes are to be marveled at because they turn out to be colorful introductions.

MintJam covered these opening themes with their own metal guitar flair. They covered CLANNAD, AIR and Kanon, so have fun!
