Uh, I`m sorry if this is not where it`s supposed to be.



Two finds that I wanted to kind of share.



One is a 14 minute, 21 MIDI? ear-copied medley.

The other is a mini-project they have with various artists. I don`t know if they still are working on it, and/or if it`s just a compilation or a actual project.

(So it`s not a single circle.)

After reading descriptions and tag, the first video is under the samidare tag.Basically, (assuming my translation capacoty didn't fail me) a samidare are midis of touhou music done by hear, trying to get as closs as possible to the original.Fist link is a video of such a samidare where the author made a medley of 21 touhou melody which also include at least 3 ending themes at the end.The video was apparently popular enough to generate related videos and by extension a tag, the Touhou 21 songs medley About the second link, basically, there was a project where people posted their own videos which must follow a specific theme :starting and ending with a circle (Japanese version mention the term "Baton Pass)".Afterward, they were made into a single video and music was added.Interestingly, said video also have the samidare tag. ^^Perhaps that for details it would be better to ask the person directly so here is its nico nico profile page :Also, welcome here. ^^
