Nether - The Dark Ages

While exploring the vast hellscape known as the Nether, 7 unique mixes from "DOOM - The Dark Ages" will play along your journey. These are custom mixes that utilize the raw audio files, making it so they're calm enough to fit the atmosphere, while getting slightly more intense as they progress. None of the songs bust out into full headbangers though, so you can still somewhat relax even in the midst of usual combat.

All original compositions of the music belong to Finishing Move Inc. This is more of a personal recommendation, but I feel this goes great with Dungeons Dimensions: Nether, even without this resource pack.
