I wish to bring forth something that's been very much under the radar for the last couple of years. The soundtrack for the Halo: Evolution motion comics The Return, Headhunters & The Mona Lisa (Parts 3, 6 & 7), as composed by Paul Lipson.

It's been sitting in his SoundCloud for the last couple of years, which can be found here: https://soundcloud.com/plguitar/sets/halo-waypoint/

But now to the main point, I've taken the time to prepare all tracks on his SoundCloud for download & offline use in FLAC (Uncompressed) & MP3 (MP3-320). I don't know if HBO is still interested in archiving such things, particularly as I am relying on the assumption that this music also falls under Microsoft's Content Usage Rules, but you never know until you ask as people say.

For immediate listening, you can find their playlists hosted on my second channel through this video: http://www.youtube.com/watch?v=GRWifUOSRTg

As for download links, here they are:

MP3 (MP3-320)

If this doesn't rest well with HBO, than I fully understand if you wish to destroy this post. Otherwise, I hope this reaches people who have wanted it, even after all this time.
