The legendary metal band NEFARIOUS has announced the addition of a new vocalist, Sean Rivera, after parting ways with their previous singer Katon W. De Pena. Rivera, known for his work with the band COFFIN HUNTERS, is described as a 'musical wizard' with a limitless vocal range and explosive stage presence. The band, formed by a supergroup of metal veterans, is excited about the chemistry and shared vision Rivera brings as they prepare to hit the stage with a new sound.

Why it matters

NEFARIOUS has long been considered one of the most influential thrash metal acts, known for their raw power and skull-crushing energy. The departure of Katon W. De Pena and the arrival of Sean Rivera marks a significant shift for the band, as they look to evolve their sound while staying true to their thrash metal roots. Fans are eager to see how Rivera's addition will impact the band's musical direction and whether they can maintain their signature intensity.

Rivera, known for his work with the traditional heavy metal band COFFIN HUNTERS, is praised by the band for his exceptional vocal range, proficiency on guitar and keyboards, and his ability to push the group in new directions. The decision to bring in Rivera was not without controversy, as De Pena cited a desire to focus on his long-running band HIRAX, while the NEFARIOUS members hinted at communication issues and the need to 'move on.' Nevertheless, the band is excited about the chemistry and shared vision Rivera brings, as they prepare to unveil a new sound that blends early thrash metal with heavy metal harmonies and influences ranging from DEEP PURPLE to BLACK SABBATH.
