SHAFT Finds The Best Music (Denpa Onna OP, by Shinsei Kamattechan)

I guess someone in the studio has impeccable taste. SHAFT are known to have amazing original OPs and EDs done by unexpected or otherwise awesome artists (such as ryo on the Bakemonogatari ed and Ootsuki Kenji on Zetsubou Sensei’s everything), and the Ootsuki Kenji to Zetsubou Shoujo-tachi album is by far my favorite anime-related musical project (to the extent that I actually own the album!).
