I've had this mix for a while now, as well as several of Dover's new mixes from the now defunct vgmix. Tears for a Moonlit Knight still stands as his best work, in my opinion anyway. It's a strange fusion of so many genres as others have noted. I was blown away when I first heard this, and still am these many months after. Others have already chimed in on why this is such a great mix, so I won't be repeating what others have said. I'll only say, this is a truly breathtaking mix, worthy of the acclaim it has gotten.
One of the best game mixes of all time. Download it now, if you already haven't. If you haven't, you're out of the loop.
