Helloween is a German power metal band formed in Hamburg in 1984. Considered one of the pioneers of the power metal genre, the band is known for blending fast-paced guitar riffs, melodic vocals, and fantasy-themed lyrics. Their most influential works are the Keeper of the Seven Keys albums, which helped shape modern European metal and inspired countless bands. Over the years, Helloween has undergone several lineup changes, including the return of original members Michael Kiske and Kai Hansen, creating a “Pumpkins United” era with three lead vocalists. The band remains a key figure in the global metal scene, continuing to release albums and tour worldwide.
