Helloween, banda alemana de heavy metal, hizo su debut en 1984 en Hamburgo, Alemania. La formación original incluía a Kai Hansen (guitarrista y vocalista), Michael Weikath (guitarrista), Markus Grosskopf (bajista) e Ingo Schwichtenberg (baterista). La combinación de riffs rápidos, estribillos pegajosos y letras épicas definió desde el principio el sonido que se conocería como power metal.
En 1985, Helloween lanzó su primer EP homónimo, rápidamente seguido por su álbum debut completo Walls of Jericho, un hito que posicionó a la banda en el radar del mundo del metal. Su sonido agresivo pero melódico cautivó a una audiencia cada vez mayor y sentó las bases para su futuro éxito.
Pero fue realmente con el lanzamiento de Keeper of the Seven Keys Part I (1987) y Keeper of the Seven Keys Part II (1988) cuando Helloween alcanzó a un público masivo y consolidó su estatus en el panteón del metal. Con la entrada de Michael Kiske como vocalista, estos álbumes mostraron una evolución hacia un sonido más melódico y maduro. Temas emblemáticos como "Future World", "I Want Out" y "Eagle Fly Free" se convirtieron en himnos para los fans del power metal.
Los años siguientes no fueron fáciles para Helloween. La banda enfrentó disputas internas y desafíos legales que culminaron en la salida de Kai Hansen, quien pronto formaría otra banda icónica, Gamma Ray. A pesar de estos conflictos, Ver BiograFia Completa
Once they killed his monster when it went into a trap
Now he's making better ones on a higher step
On a warm summer day the doctor went away
To a place where he could make it real
His assistant's hips were nice
So he cloned her once or twice
Now his hips are aching what a deal
Dr. Stein grows funny creatures
Lets them run into the night
They become great
Rock musicians
And their time is right
Sometimes when he's feeling bored
He's calling it a day
He's got his computer and they do in their own way
They mix some DNA, some skin and a certain spray
You can watch it on a laser screen
And the fellow's blue and gray
Or sometimes pink and green
Just check it out on Halloween
Dr. Stein grows funny creatures
Lets them run into the night
They become great politicians
And their time is right
One night he cloned himself
Put his brother on a shelf
But when he fell asleep that night
It crept up from behind and thought "Well, never mind "
Took a syringe and blew out his life
Dr. Stein grows funny creatures
Lets them run into the night
They become a great possession
And their time is right
Dr. Stein grows funny creatures
Let's them run into the night
They become a great oppression
And their time is right
