Martin O' Donnell's musical prequel for Destiny was recently leaked, and it's pretty fucking awesome if you ask me. Way way way above anything Halo in terms of composition and instrumentation. It's a fucking masterwork, and those kikes at Activision kept it from the general public for 5 years just to spite the man who made it.
