【東方 Arrangement】 Forbidden Magic (Stage 4 Boss Theme)

Artwork by Hrusa:   / hrusaart   Art commissioned by me. Yuki and Mai's boss theme when fought together. It's been a while since I last uploaded a Touhou arrangement, though I never really stopped making them (I have a whole folder full of them). I tried to give it an "icy" feeling with some of the instrument choices.
