Tyrian Music
Tyrian is a vertical shooter by World Tree Games released in 1995 and published by Epic games. I have fond memories of the music (and game) but was having trouble finding a copy of the soundtrack as MP3s (etc).
Luckily this site has a copy of the original LDS (Loudness Sound System) files and using Foobar2k + AdPlug input component I was able to get them to play (note: the component expects the extension to be be ldsa). While I was at it, I also made a copy of them as MP3 files.
You can listen to the music below, or download a zip file of all the MP3s: tyrianlds-mp3.zip (40MB)
