Electromagnetic noise recordings

Ghost Shells – VLF band radio noise from geomagnetic “whistlers” and lightning strikes
Data Storm – Unidentified VLF band data noise

Extreme contrasts of amplitude and frequency in the recording on side one placed severe constraints on the feasibility of their reproduction on vinyl. Ash International were advised by the pressing engineer that the width of grooves required imposes a maximum playing time of just over 5 minutes. Includes 4 x 11 insert about the recording.
