This is a very minor modification to the main theme from NX2:Storm of Zehir that removes the blaring trumpet at the beginning. I think the music from SoZ is generally excellent, but that trumpet just drives me crazy, especially when having to test a module over and over again. It will be interesting to see if it's just me, LOL.
Just put this BMU file in your ..\My Documents\Neverwinter Nights 2\music_X2 directory and it should work.
