Hades is made by Supergiant Games.
This is ingame footage for a song that Orpheus randomly performs in the House of Hades. He is voiced by Michael Ailshie (speaking) and Darren Korb (singing).
Hades: Original Soundtrack doesn’t seem to have this version, but you can find the other songs in the makers own website here:
