Supergroup NEFARIOUS, featuring Rick Hunolt (EXODUS, DIEHUMANE), Doug Piercy (HEATHEN, ANVIL CHORUS), Tom Gears (BLIND ILLUSION, ANCIENT MARINER), and Will Carroll (DEATH ANGEL) on drums, showcased their new vocalist Sean Rivera in a thrilling concert at DNA Lounge in San Francisco on January 3.

The event was live-streamed by Walter Morgan.

Rivera stepped in as the replacement for Katon W.

De Pena of HIRAX, who sang on NEFARIOUS's debut album 'Addicted To Power'.

Doug Piercy expressed his excitement about Rivera's addition to the band in a statement: 'We wanted someone who could be in the room with us — creating, rehearsing, and ready to play.

It's hard to get tight as a band when they can't rehearse on the regular.

The Bay Area has always thrived on that energy, and now we've got it.' Will Carroll spoke about the singer switch during an appearance on Zetro's Toxic Vault, stating: 'Things didn't work out [with Katon]...

But it was a communication thing that was really the problem.

He would not talk to us for months at a time...

So we took that as he didn't wanna be in the band.' NEFARIOUS is set to embark on a full European tour in August/September 2026, starting with the legendary Alcatraz festival in Belgium.
