I Am Rapture, Rapture Is Me is the Official Bioshock Score that was released on vinyl in February of 2010. Some of the tracks on this score were available for a time on 2K Games website but are no longer available. This is our second vinyl audio rip that we've done now and it turned out well, there wasn't many of them but I removed most of the obvious audio pops that could be heard during playback but this is a recording of a vinyl so like the "Ratchet & Clank" vinyl we uploaded, it's not going to be 100% free of those such as a rip of a CD or game files would be. The price is getting up there for the vinyl but you can still pick it up between $50 - $80 on Amazon or ebay.
I haven't had the chance to listen through it yet but even after a good 6 years or so since I've played the first Bioshock, I still listen to Cohen's Masterpiece regularly and I'm looking forward to finding new tracks in "I Am Rapture, Rapture Is Me" to add to my video game music playlists. Enjoy!
