Inon Zur has an awesome name. He's also an award-winning composer. An award-winning composer who also happens to working on the Fallout 4 soundtrack.
Listen to him play Fallout 4's latest theme song on his big-ass piano. It sounds pretty good.
Zur has been doing the music for Fallout since Fallout: Tactics, and he's been doing a pretty good job of it. Along with this video, Bethesda has put together a pretty cool profile on Zur and his work up until this point. You should check it out.
