When I was searching on this, I came across someone mentioning an alpha and a pre-alpha version of UT. Someone did link the music from the beta but after all these years they were dead. Did they ever release demos/beta's on any PC magazines back in the day?
It was strange that this topic came up now, because I was trying to work out how accurate all my credits to the various musics were. I was trying to figure out a definitive credit list to all the music (tracker based), from the games, mods and map packs. I found I was missing some, some inaccurate credits and some I plain didn't even know about, ie beta's..
It still reminds me, just how good the music for the Unreal games were back then (and still are)...
