Metal music is a genre of rock music that emerged in the late 1960s and early 1970s. It is characterized by heavy guitar riffs, powerful drumming, and strong vocals. Bands like Black Sabbath and Led Zeppelin are often credited with pioneering the style, which has since evolved into various subgenres, including heavy metal, thrash metal, and death metal. The themes in metal music often explore darker subjects, such as mythology, war, and personal struggles. Metal concerts are known for their energetic atmosphere, with fans often participating in activities like moshing and headbanging. Over the years, metal has developed a dedicated global following and continues to influence many artists across different genres.
