I checked the official site at www.myst3.com . The makers of the series have always provided interesting insight into their works, and also this time there's plenty of background information at the website. The music section contains a brief interview with composer Jack Wall, who talks a bit about scoring games and Exile in particular, which will use orchestral music.

He says:
I also like the scores to the Matrix (Don Davis), The Fifth Element (Eric Serra), and Waterworld (James Newton Howard). They each have elements that I think may fit nicely into the surreal worlds of Myst.

I haven't heard Waterworld yet, but I find Serra's Fifth Element works very well in the film, and I am a big fan of Don Davis' Matrix score. Having stuff like this in a computer game (and the Myst series has a very high standards) is fascinating.

The download section has a trailer for download (yes, that's Brad Dourif at the end! ), and the bit of music sounds promising, though it doesn't say if this is original music by Michael Wall.

Oh, and Bri? You might not want to wait for this... it's that good.

Also, for Myst lovers, if you have not read the trigoly of "Myst" novels, I suggest you do. They are great fun to read and expand the "Myst" story.

I am just re-working all the sound clips, so they will be up very soon.
