King Diamond has announced that Gus G. — the Firewind founder who spent eight years as the late Ozzy Osbourne’s lead guitarist — is the band’s new guitarist, and will compose, record and tour with King Diamond going forward. The announcement confirms the end of Andy LaRocque’s four-decade run alongside the King, the longest and most defining creative partnership in the band’s history, dating back to 1985. Gus G. is already writing with King Diamond on new music, and he will continue with Firewind and his solo career alongside his new role.

The Announcement
In a statement released today, the King Diamond camp confirmed that Gus G. joins as a full member — not a touring hand — with composing, recording and touring duties all on the table.
“It’s a Big Honor for me to Welcome Gus G. as our new guitarist,” King Diamond said. “Gus will still continue with all his current projects, Firewind, Solo Project etc. No restrictions, just careful planning. We are already working with Gus and I simply can’t wait for you to hear all the new King Diamond music with him playing guitar on it!!! Stay Heavy — King”
The statement also paid extended tribute to LaRocque, extending “deepest gratitude and utmost respect” for what it called an extraordinary 40-year contribution that left “a permanent and irreplaceable mark” on the band’s legacy and on heavy metal as a whole. Notably, no reason was given for the departure, and as of press time LaRocque has not issued his own statement.
The new King Diamond lineup:
- King Diamond – vocals
- Gus G. – guitars
- Mike Wead – guitars
- Pontus Egberg – bass
- Matt Thompson – drums
End Of An Era: The LaRocque Legacy
It is genuinely difficult to overstate what Andy LaRocque means to King Diamond. The Swedish guitarist joined in 1985 — his recorded audition was the solo on “Dressed in White” from the debut album Fatal Portrait — and from that moment forward he was the King’s essential musical foil. Fatal Portrait remains the only King Diamond album without a LaRocque writing credit; everything after it, from the neoclassical nightmares of Abigail and “Them” through 2007’s Grammy-nominated Give Me Your Soul…Please, carries his fingerprints. Through more than fifteen lineup changes across four decades, the two constants in King Diamond were the man in the paint and the man on his right.
Beyond the band, LaRocque built a parallel legacy as a producer and engineer at his Sonic Train Studios in Sweden, and famously lent his lead work to Death’s classic Individual Thought Patterns at Chuck Schuldiner’s personal request. This is not a sideman leaving. This is a co-architect.
The Lex Legion Timeline
Here’s the context the press release doesn’t mention — and the part longtime fans will be chewing on. Back in March, LaRocque surfaced in Lex Legion, a new band uniting him with fellow King Diamond alumni Mikkey Dee, Pete Blakk and Hal Patino — four-fifths of the beloved late-’80s lineup that recorded “Them” and Conspiracy — fronted by Pagan’s Mind vocalist Nils K. Rue. At the time, it read as a fun legacy side project. Four months later, LaRocque’s chapter with King Diamond is over.
To be clear: no one has connected those dots officially, and neither camp has stated any reason for the split. But the timeline now tells its own story — while King Diamond moves forward with Gus G., LaRocque already has a band full of old friends, over 40 years of shared history, and a debut album in the works.
Who Is Gus G.?
If you were building a replacement for a legend in a laboratory, the resume would look a lot like this one. Born Konstantinos Karamitroudis in Thessaloniki, Greece, Gus G. founded Firewind more than two decades and ten studio albums ago, then spent 2009 to 2017 as the late Ozzy Osbourne’s lead guitarist — contributing to the Grammy-nominated Scream and standing as the second-longest-serving guitarist in Ozzy’s solo career behind only Zakk Wylde. Add six solo albums, guest spots with Bruce Dickinson, Arch Enemy, Doro and In This Moment, covers of every major guitar magazine, and a Golden God award for Best Shredder, and you have one of the most decorated players of his generation.
The “no restrictions, just careful planning” arrangement tracks, too — Gus G. said earlier this year that he had just finished a new solo record and was wrapping a new Firewind album, both expected before year’s end. The man does not sit still, which may be exactly what a band deep in an ambitious multi-album concept needs.
What This Means For The Horror Trilogy
The timing is the real story for fans. King Diamond is deep into his long-promised Horror Trilogy, which opens with Saint Lucifer’s Hospital 1920 — the project that produced the 2024 single “Spider Lilly” featuring Myrkur, with its video shot at the notoriously haunted Pennhurst Asylum. The King has previously detailed ten new tracks in the works for the album, and the road to this point stretches back years — through shifting timelines for new King Diamond and Mercyful Fate material that fans have tracked with growing impatience.
Today’s announcement makes one thing explicit: the band and Gus G. are “already deep in the creative process together,” and new music from the full lineup is coming. Whether that means Gus G.’s leads will define Saint Lucifer’s Hospital 1920 itself — or the chapters beyond it — is the question every fan of the most theatrical showman in metal will be asking until the King answers it.
One era ends. Another begins. And somewhere in Sweden, four-fifths of the “Them” lineup just became the most interesting new band in metal.
