It is described by AllMusic as "extremely fast, abrasive, and technically demanding" music.  - Power metal is a subgenre of heavy metal combining characteristics of traditional metal with speed metal, often within symphonic context. Generally, power metal is characterized by a more uplifting sound, instead of the heaviness and dissonance prevalent in styles such as doom metal and death metal. Power metal bands usually have anthem-like songs with fantasy-based subject matter and strong choruses, thus creating a theatrical, dramatic and emotionally "powerful" sound. The term was first used in the middle of the 1980s and refers to two different but related styles: the first pioneered and largely practiced in North America with a harder sound similar to speed metal, and a later more widespread and popular style based in Europe (especially Scandinavia, Germany, Greece and Italy), South America (especially Brazil and Argentina) and Japan, with a lighter, more melodic sound and frequent use of keyboards.  - Heavy metal (or simply metal) is a genre of rock music that developed in the late 1960s and early 1970s, largely in the United Kingdom and the United States. With roots in blues rock and psychedelic/acid rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Heavy metal lyrics and performance styles are sometimes associated with aggression and machismo.  - The new wave of British heavy metal (commonly abbreviated as NWOBHM) was a nationwide musical movement that started in the United Kingdom in the late 1970s and achieved international attention by the early 1980s.

The songs usually use fast percussive beats and low-register guitar riffs, overlaid with shredding-style lead work.
