This is the case of a group I wished I had known sooner. The story of how I came to know about it is kind of funny, I have japanese friends we speak to each other in japanese and we are all huge Touhou nerds. So for the funsies one of them made me play a game, he would show me Jpop from the 80's (One of ZUN's biggest inspiration for his music as far as I'm aware) and I would have to guess which Touhou music it inspired. So he showed me this one, being the main reference of Eirin's theme Gensokyo Millenium - History of the Moon. When I stumbled across this song, I was already struck with appreciation for the group, it's wacky, mysterious in a way and I like the electronic feeling to it.

My favorite part is the piano at the end that slowly goes out of sync with the music, doing its own thing until it goes completely out of control. I recommend highly that music and the group, I love it a lot.
