Gus G., the Greek guitar virtuoso who once made his living as Ozzy Osbourne’s guitarist and has led the power metal outfit Firewind for years, has become the new guitarist of Danish heavy metal cult legends King Diamond!
The move came after Andy La Rocque, King’s longtime guitarist and songwriter, decided to leave King Diamond.
Few guitarists have shaped the sound of King Diamond as decisively as Andy La Rocque, so his departure marks the end of an era for the band. On the other hand, with Gus G. coming aboard, King Diamond are opening a new chapter in the band’s long-running career, and it’s a more than exciting one.
On April 24, 2026, Gus G. released his new album, his fifth studio album overall, “Steel Burner”.
Gus G., the Greek guitar virtuoso whose real name is Konstantinos Karamitroudis, won a place in the hearts of true metal fans some 25 years ago, when he blew everyone away with his guitar chops on the first three albums by power metallers Dream Evil and Mystic Prophecy, as well as on all eleven albums by his main band Firewind, which he actually founded while he was still playing with those two groups. But above all, Gus G. became known worldwide when none other than the Prince of Darkness, Ozzy Osbourne, took him into his ranks in 2009! Gus G. recorded the album “Scream” with the Prince of Darkness! He played guitar for Ozzy right up until 2017! Gus G. has also released five solo studio albums.
