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. Journalist Geoff Barton coined the term in a May 1979 issue of the British music newspaper "Sounds" to describe the emergence of new heavy metal bands in the late 1970s, during the period of punk rock's decline and the dominance of new wave music.  - Holy Moses is a German thrash metal band. They are well noted for being fronted by Sabina Classen (it is rare for a woman to be a singer in thrash metal) and for being one of the very first German thrash metal bands.  - Thrash metal is an extreme subgenre of heavy metal music characterized by its fast tempo and overall aggression. The songs usually use fast percussive beats and low-register guitar riffs, overlaid with shredding-style lead work. The lyrics often deal with social issues and reproach for The Establishment, using direct and denunciatory language, an approach borrowed from hardcore punk.  - AllMusic (previously known as All Music Guide or AMG) is an online music guide service website.
