High Quality Content by WIKIPEDIA articles! Metal Hammer (sometimes MetalHammer) is a monthly heavy metal magazine published in the United Kingdom by Future Publishing, and in several other countries by different publishers. It features mainstream and more unusual bands from the wide spectrum of metal music. It is the second-largest selling rock magazine in the UK behind Kerrang! and was often viewed as the more underground magazine, but in recent times has moved towards the mainstream metal market which it originally shunned. In Germany, Metal Hammer has been the market leader since it was launched in 1984.
