Speed Metal is a subgenre of heavy metal music characterized by its fast tempo and dynamic, intense energy. It emerged in the 1980s and constitutes a blend of technical prowess and aggressive riffs. It is often associated with bands like Motörhead, Judas Priest, and Helloween, who laid the foundations for the genre. The vocals are usually high intensity, while the drums and guitars play faster and more complex rhythms, giving a warlike feel.
