Fallout 1 and 2 composer Mark Morgan has a little side project that he calls his "Vault Archives." His goal was to remaster all the songs he composed for the Fallout series. Now it seems that he's done with his project, and he was kind enough to share the results with everyone.
The OSTs for both games are available as a free download on Aural Network. These 24 tracks are remixed and remastered, full-bandwidth tracks from the classic games, available to you at no cost. What I've heard so far sounds amazing. Go get it!
