Bad Apple!!, created by ZUN in 1998, was originally included in the soundtrack of the 4th Touhou Project game – Lotus Land Story. Back then the soundtrack was electronically composed, without vocals, until Masayoshi Minoshima remixed the tune, featuring Nomico’s vocal and released it in an album called Lovelight.
The song went viral after Nico Nico Douga user Anira released the PV with 3D moving models and silhouette shadow art.
I have to say that this mesmerizing PV contains the artistic DNA from various talented peeps.
