I'm a very plainchant-ish / praise and worship person, but you've brought me back to middle ground with this piece. I'm going to go listen to some more things like these at some point.
In all honesty, though. This thing is sublime. The voice especially, and I was quite surprised to hear this kind of quality coming out from a MIDI voice. I do wish this thing had an ending, though -- a definitive ending which could either signify personal judgement, or salvation, either way. I imagine that'll justify the piece far better.
It's lovely as is, and I've enjoyed listening to your pieces -- I enjoyed listening to this one!
