2010 album from the German Power Metal band. Founded in 1984, Helloween are pioneers in their field, and the inventors of German Melodic-Speed-Metal. 7 Sinners is the band's 15th Studio album, and is definitely one of the fastest and hardest albums in the bands history. 7 Sinners bursts with vitality, and presents sensational novelties and still is a record in best Helloween tradition. The so-called mortal sins are the overall concept of the album. 7 Sinners plays light-heartedly with the heavy symbolism of the seven main vices. This is also a specialty of the band: touching dark themes and turning them into something constructive, owed to their positive attitude.
