866 - Helloween I´m Alive 1987

Keeper Pt.1" was the first Helloween-album with Michael Kiske on the vocal helm. The first two earlier releases the self-titled EP in 1985 and "Walls of Jericho" in 1986 were a style resulted form a combination between Metallica and Iron Maiden but it's on this album that their songwriting appears to be progressed and matured, and they take an important step in their musical career and with this album they bring a new genre to the metal scene: Power Metal.
The opening riff of "I'm Alive" is indeed a strong way to kick in the whole album.
