Welcome to the channel of Clockorkzone. Enjoy your stay in the bowels of the internet.
This channel focuses on, if we are to be objectively speaking, the OST and arrangements thereof from a series of quite obscure and not all that great StGs, namely, Seihou Project, Shuusou Gyoku/Kioh Gyoku that only ever whose only claim to fame is that ZUN graced them with His presence and cameos (sarcasm alert), and his actually quite godlike composing skills. Which means that there is good music to be enjoyed.
If you were looking for a good Touhou-styled StG that isn't Touhou itself, play Hitogata Happa. I'm not joking when I say that there is some serious problems with each game of the Seihou Project, but I shall say that they also have their merits. So, lose yourself in this vortex of music. And, have fun.
...wow, I think I overdid the posh speak a little.
