Funnily enough, I actually only found out about these great little tracks via a website offering them for download whilst searching for Baldurs Gate remixes.
The only other one I found at the time was a sweet little piano remix at VGmix.com.
Those Tiax quotes are freakin' hysterical. It was even made funnier by the fact that in my last run through the game, I had my first experience with using him in chapter 6. Dropped him for Jet Laya then finished Darkside, then promptly picked him up again and finished a couple of Ulgoth beard's quests and the game. Considering that most of my party other than the PC was Chaotic Good or Neutral, hearing their reactions to the EgoMania of TiaxDom was fantastic.
