Trent Reznor

Trent Reznor is the frontman of the band Nine Inch Nails. As a fan of id Software and vice versa, he was asked to design the music and sound effects for Quake. Quake's nailgun ammo boxes also feature the NIN logo on them.

Reznor later did the initial sound design for Doom 3, but his material was eventually scrapped and replaced with other alternatives. Reznor's work on Doom 3 can be heard in the Doom 3 alpha builds, as well as via an unofficial sound pack mod.

In addition, former NIN drummer Chris Vrenna wrote and recorded the Doom 3 theme song with his band.
