On this day, 2 November 1988, German power metal band played Cardiff’s St David’s Hall. The band had just released their third studio album Keeper of the Seven Keys: Part II
The album sold well, and success bloomed all over Europe, Asia, and even the United States. The album went gold in Germany and reached No. 108 in the US.
Two singles were released from the album, "Dr. Stein" and "I Want Out". "Dr. Stein" has a very long and moody solo, played with a blues tinge, very unlike other solos on the album, as well as an organ solo. "I Want Out" remains the band's best-known song, and has been covered by several metal bands, such as Gamma Ray (which Kai Hansen formed after leaving Helloween itself), Unisonic, HammerFall, LORD and Sonata Arctica. It is their last album to feature Hansen until 2021's self-titled album.
Founded in 1984 in Hamburg by members of bands Iron Fist, Gentry, Second Hell and Powerfool. It is said that the band is one of the most influential European heavy metal bands of the 1980s.
Its first lineup consisted of singer and guitarist Kai Hansen, bassist Markus Grosskopf, guitarist Michael Weikath and drummer Ingo Schwichtenberg.
