I am not really sure what to say or think. Over the last day I have tried writing a reply to this topic but had to delete it every time because, gods knows why.
Halo to me was way more than a video game to me, and the music was a uniquely part of that. Not a game that was heavy on story, but I feel that Halo, more than any other video game I have played my entire life, told it's story through the audio-visual moments.
For me it's the interactive text book example on how to do sound design.
Example would be that moment on the second level upon landing on Halo. You make your way up to some structures, clear the Covernant, and a few dropships come in with a Warthog. As you enter the Warthog, this psuedo-tribal music starts playing with bombastic drums, electric guitar riffs and an intense beat. This is a sci-fi world, and already I feel the music is breaking all the conventions I know about music in this genre.
Suffice to say, the chanting monks, the haunting melodies of the desolate wastelands. I loved it all, and still do to this day.
My earliest memories are those of Koji Kondo, and the gaming composers I have listened the most too in my life is Harry-Gregson Williams (Metal Gear Solid series) and Jeremy Soule (KOTOR, Morrowind, Oblivion, Skyrim, Guild Wars 1 & 2) and Jesper Kyd (Hitman, Freedom Fighters, Assassins Creed 2) but Marty's music.
This is a sad day for Bungie. Really. I've been a Bungie fan since the early Mac days with Marathon. I am super sad about this. Really, a lot more than I should be. I am not one to get sad when my favorite bands break up - After all, these things happens for a reason, and it might be why I am sad about this. I don't understand what happened, so my brain think it could have been avoided.
On the bright side, we got many good years with his music, and maybe he will find another place to keep making music.
