Helloween is a German power/speed metal band founded in the early 1980s by members of Iron Fist and Powerfool. Helloween are known as the inventors of power metal.
The original line-up featured Kai Hansen (Vocals/Guitars), Michael Weikath (Guitars), Markus Grosskopf (Bass) and Ingo Schwichtenberg (Drums). In 1984 the band had signed a deal with Noise Records (see 1984 in music) and recorded two songs for a Noise compilation record called Death Metal with bands Hellhammer, Running Wild and Dark Avenger. The two tracks were "Oernst Of Life" by Weikath, and Hansen's "Metal Invaders" which later on ended up in a faster version on the band's first full-length album.
