Trent Reznor

Trent Reznor is an industrial rock musician in the band Nine Inch Nails. A big fan of the Doom series, he was hired by id Software to design the music and sound effects for Quake. He also worked for a while on the sound design for Doom 3, none of his sounds made it into the final release, but his early work on the project is available from a leaked alpha version of Doom 3. Fans have created a Doom 3 mod pack which puts those sounds back into the game.
