Michael C. Salvatori (born 1954) is an American composer best known for his collaboration with colleague Martin O'Donnell for the soundtracks to the Halo video game series.

He also composed music for Destiny 2 (2017) as well as its expansions, Forsaken (2018), Shadowkeep (2019), Beyond Light (2020), The Witch Queen (2022), Lightfall (2023), and The Final Shape (2024).

Salvatori remained at TotalAudio to manage the business aspect of the company, and shortly after O'Donnell joined the team, Bungie was bought by Microsoft.

[6] For the music to Halo 3: ODST, O'Donnell began work on crafting the game's themes before Salvatori joined the team in February 2009.

Once the duo felt they had enough material, the Chicago-based Salvatori flew to Bungie in Seattle to complete the arrangements and record live musicians.

"It was a bit intimidating at first," Salvatori recalled, "because in previous Halo games if new ideas weren't coming, I could always dust off an old one and give it a new spin.

While the game's setting in Africa inspired some percussion pieces, the team was interested in a sparser atmosphere, which Salvatori described as "a bit darker and less epic".

[13] Halo 3's soundtrack was released in November 2007, and featured a fan contribution that was the select winner from a pool of entries judged by O'Donnell, Rodgers, and others.
