Mayhem’s Attila Csihar Believes He Has Late Slipknot Drummer Joey Jordison’s Final Recordings

Mayhem vocalist Attila Csihar believes he has the final recordings of late Slipknot drummer Joey Jordison.

Csihar and Jordison were bandmates in Sinsaenum, a blackened death metal band Jordison founded in 2016 that he was a member of until his passing at age 46 in 2021.

The recording in question is a cover of the 1975 Kraftwerk song “Radio-Activity,” stemming from a time when Csihar and Jordison were considering starting a new band called Electhrone, which would have explored goth and industrial influences.

In an interview with Metal Hammer, Csihar said, “[Jordison] had a unique taste in music, because he didn’t just know all the metal bands but the industrial and goth-like bands. Bands like Skinny Puppy and Front Line Assembly and Suicide Commando, who were inspirational to me when I was in Plasma Pool.

He added, “Electhrone was more of an industrial metal kind of thing and I think I have his last recordings ever. We did covers of Kraftwerk’s “Radio-Activity” with Joey on drums and Skinny Puppy’s “Assimilate,” which we did for my friend Nysrok Infernalien and his band Alien Vampires, who I played with in Aborym.”

Csihar continued, “We were supposed to do more though, and it’s all only at the demo stage. I really miss him. I invoke him alongside [late Mayhem members] Euronymous and Dead and invite him to the Mayhem shows as the people from the beyond.”

Mayhem’s newest album, Liturgy of Death, was released in February 2026. We named it one of our 20 best metal & hard rock albums of the year so far back in June.

The late Jordison, meanwhile, ranks No. 27 on Consequence‘s list of the 100 Best Drummers of All Time.
