Disc 1 is a lovely compilation of natural VLF radio signal (audio-frequency) of Earth's Magnetosphere, recorded by Stephen P. McGreevy, N6NKS in the summer of 2000 in Alberta, Canada.
This album follows "Electric Enigma" (1996), "Auroral Chorus I" (1998), and "Auroral Chorus II: The Music of the Magnetosphere" (2000). All my other MP3 albums pertaining to Natural-VLF-Radio are on archive.org.
Disc 2 (on this site) contains natural VLF radio field-recordings from northern Alberta and Saskatchewan, Canada, June/July 2001. The Music of the Magnetosphere.
