"Magicant" but it's the Hallow's End version
That's right, I'm most likely the first person here on YouTube to upload the full OST of H.S.'s EarthBound/Mother 2 hack named Hallow's End!
This song is heard at the Magicant-like area (as I call it), the first 'twisted' area that Sally, Clyde and Craig enter in the Mereseti Building. This song has had an earlier version in Hallow's End v1.02 with different instruments, but unfortunately, I've been unable to rip it due to the ROM of that version not working on ZSnes and Snes9x.
I ripped the song by using the steps of the following tutorial: https://youtu.be/rafk1FNYSdU

This song has originally been composed by Keiichi Suzuki and Hirokazu Tanaka, and was originally edited by H.S. for Hallow's End. Fair use.
Enjoy, like, etc.! :)
