This German heavy metal outfit formed back in '65, before the genre even existed. Their debut dropped in '72, but it wasn't until the end of the decade that the band truly began to attract attention. The '80s were different and the group hit huge on the international stage, releasing successful albums filled with monster anthems and power ballads. The combination of singer Klaus Meine's soaring vocals, well-executed pop-metal songwriting and flashy guitar pyrotechnics made the Scorpions irresistible, leading to worldwide sales of over 100 million.
