Two pieces by 柊秀雪, (aka Shusetsu Hiragi) Anyone knows his Doujin CDs? His circle As/Hi Soundwork have released four albums named "Touhou Small Compilation for Piano". I've collected all of them(two from Tokyo and the other two I booked online). They are great anyway: His piano arrangements are neither flaunty nor complex. However, this kind of music is what can best represent Gensoukyou's unrestrained and rural atmosphere. Here're two pieces from this set of albums. Fantaisie in B Flat Minor(Original: The Capital City of Flowers in the Sky(天空の花の都), stage 4 of PCB)
【Nocrturne】衛星カフェテラス(Satellite Café Terrace)
Actually ZUN's Music CDs are all worth to listen. My favorite one is Magical Astronomy.
