Melodic death metal (also referred to as melodeath or MDM) is a heavy metal music style that combines elements from the New Wave of British Heavy Metal (NWOBHM) with elements of death metal. The style was developed during the early and mid-1990s, primarily in England and Scandinavia. The Swedish death metal scene in particular did much to popularize the style, which soon centered in the "Gothenburg metal" scene in Gothenburg, Sweden.
