Deeply Epic
I saw in one of the earlier comments you said this was all produced digitally. You just took the top place among my heroes, because this is the sort of thing I try to tell people is possible, but they don't listen to me. I might have to get myself a copy of this Renoise once my new computer gets in, because What I've always wanted to do is make more natural instrumental music, but I don't have the tools to do such things, but this proves otherwise.
Anyways, about the song itself, I have yet to listen to the other four parts, but I think I will, because this is awesome in so many more ways than I can describe. I love the basic composition as well as the layered strings, although it seems to be a bit much as a replacement for a lead guitar a little later on, until about 5.14. Wonderful work, otherwise.
