Gamma Vortex – Undertaker (Digital EP – Scanner / Dark Dimensions)
Gamma Vortex is a Swedish solo project by Martin Rudefelt, best known for his work with Cryo. “Undertaker” is an EP originally released in 2024 on Dungeon Production and re-released in late 2025 on Scanner.
Musically, Gamma Vortex has little in common with Cryo. This is dark EBM, situated somewhere between Frontline Assembly and Yelworc. There’s a perfect balance of power and atmosphere, particularly on the two opening tracks. The vocals have a ghostly quality, yet remain commanding and impactful. In addition to the four original tracks, the EP includes two excellent remixes by Bagger 258 and TUKT, adding fresh perspectives to the material.
I wasn’t familiar with Gamma Vortex before, but “Undertaker” proved to be a very compelling EP that I can highly recommend. (Rating:8).
