There’s a certain upper echelon of names that come up when we think about modern composers, and Marty O’Donnell is certainly one of them. From Flintstones Vitamins and Mr. Clean jingles to immersive orchestral masterpieces, he’s done it all.

But he’s also much more than just another studio guru or commercial composer. More of an all-around audio director, O’Donnell takes pride in owning the entire audio experience from sound design and music to voiceover dialogue and beyond. Together with his business partner Michael Salvatori, O’Donnell formed Chicago-based Total Audio. Throughout his career, he has worked with a slew of musicians and voice actors including Paul McCartney, Keith David, and Steve Vai. Marty has also had run-ins with well-known artists like Justin Timberlake.

“During the Halo 2 development, lots of folks came to Bungie to get a sneak peek,” O’Donnell said. “Justin Timberlake stopped in my studio, and we talked about music and he played my piano. Super talented guy, and quite good-natured.”

O’Donnell’s professional footprint in video games can be traced back to 1993. A young 18-year-old named Josh Staub — son of radio host Dick Staub and a gaming industry intern at the time — introduced him to a beta version of a PC game called Myst.

After playing the game for a couple of hours, O’Donnell was inspired by the exceptional visuals, music, and impressive sound design. He describes this as the moment it clicked for him—creating music for video games would be his future.

Over the next two decades, he went on to produce music for games such as Riven, Myst II, Marathon, Septera Core, Oni, Halo, Destiny, and more, all of which incorporated his musical genius.

But among the trove of great works, one game’s music came to define a generation.

That game was Halo.

We’ve all heard the Gregorian chant and tried to emulate it with whatever acoustical aid the shower has to offer. Written and composed by O’Donnell and his partner Salvatori, Halo’s title track and overarching musical theme would captivate gamers worldwide. O’Donnell’s talent continued to permeate the soundscapes and scores through the next four Halo games and beyond.

The Marty O’Donnell Collection, WATA’s newest pedigree, celebrates more than 20 years of musical genius. And it represents games, soundtracks, and film works from O’Donnell’s personal archives.

There are a couple of milestones that this pedigree achieves: It’s the first pedigree attributed to a music composer by any media grading company, and it’s also the first time a pedigree holder has hand-signed each of the labels.

“I can’t recreate the past, but I can preserve some of the important relics from my career—games, music, and other memorable items that have deep meaning for me personally,” O’Donnell said of the personal significance this pedigree has for him. “I’m so happy to know that all these memories can be part of my future legacy.”

Without further ado, let’s walk through some of the incredible games which make up The Marty O’Donnell Collection pedigree.

Halo: Combat Evolved Launch Team Copy – Factory Sealed
This is no ordinary copy of Halo. The “Not For Resale” text indicates that it is an Xbox Launch Team employee copy; these were distributed or sold exclusively to Microsoft employees. Out of the many hundreds of copies of Halo WATA has graded, only 24 of those have been Launch Team copies. Furthermore, only 3 of those 24 copies have achieved a 9.8 A+ grade. Factory-sealed examples have previously sold for over $100,000 at auction.

Halo: The Movies DVD – Factory Sealed
Considered one of the rarest pieces of Halo memorabilia, this DVD was distributed exclusively to Bungie employees during the development of Halo 2. It’s believed only a couple hundred copies were produced. Since most of these DVDs were likely opened and watched, there are only a handful that exist in factory-sealed condition.

Halo 2 Collectors Edition – Factory Sealed
With more than 8 million copies sold, Halo 2 was the best-selling first-gen Xbox game. O’Donnell happened to keep a Collectors Edition copy, unopened, in his archives for the past 20 years.

Halo 3 – Factory Sealed
This factory-sealed first print copy of Halo 3 is sure to be on any collector’s wish list. This copy being owned by O’Donnell himself makes it a true 1-of-1 example.

Myth: Total Soundtrack – Factory Sealed
Not only is this soundtrack incredibly difficult to find but this copy is factory-sealed to boot. The soundtrack’s final track is the Halo Theme. Halo: Combat Evolved would not be released until two years after the release of this soundtrack, making it the first time the public had access to music for Halo.

Golem – Factory Sealed
Developed by Highwire Games, O’Donnell’s video game development company, this represents one of his most recent works. Golem is a visually stunning VR game with an exceptional soundtrack and sound design.
