At the Mountains of Madness
The self-penned "At the Mountains of Madness" was based on the 1931 novella "At the Mountains of Madness" by horror writer H. P. Lovecraft, after whom the band had named themselves. Written by Edwards, Michaels and lead guitarist Tony Cavallari, the song featured some chaotically acrobatic vocal interplay and made ample use of swirling, echoed reverse tape effects, which served to highlight the song's sinister subject matter.
