Electrical storm, Perth

This recording captures the sferic sounds from an electrical storm that occurred on 30.03.2025. The fizzes, crackles and zaps are from natural electrical phenomena, specifically broadband electromagnetic (EM) impulses caused by lightning discharges, that were detected via a homemade receiver I adapted from the Shortwave Collective’s Open Wave-Receiver.  There are 3 recordings, the first half is prior to a power blackout, the second half is after - showcasing the atmospheric sounds without human-made EM noise. The third recording was taken with an ultrasonic mic capturing the rumblings and movements which provides the base notes of this piece. Recorded by Aliesha King.
