Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted and low-tuned guitars, played with techniques such as palm muting and tremolo picking; deep growling vocals; aggressive, powerful drumming, featuring double kick and blast beat techniques; minor keys or atonality; abrupt tempo, key, and time signature changes; and chromatic chord progressions. The lyrical themes of death metal may include slasher film-style violence, political conflict, religion, nature, philosophy, true crime and science fiction.
Speed metal is an extreme subgenre of heavy metal music that originated in the late 1970s from new wave of British heavy metal (NWOBHM) roots. It is described by AllMusic as "extremely fast, abrasive, and technically demanding" music.
Progressive metal is a broad fusion music genre melding heavy metal and progressive rock, combining the loud "aggression" and amplified guitar-driven sound of the former with the more experimental, cerebral or "pseudo-classical" compositions of the latter.
Thrash metal is an extreme subgenre of heavy metal music characterized by its overall aggression and often fast tempo. The songs usually use fast percussive beats and low-register guitar riffs, overlaid with shredding-style lead guitar work. The lyrical subject matter often includes criticism of The Establishment, opposition to armed conflicts, and at times shares a disdain for the Christian religion with that of black metal. The language is typically direct and denunciatory, an approach borrowed from hardcore punk.
Power metal is a subgenre of heavy metal combining characteristics of traditional heavy metal with speed metal, often within a symphonic context. Generally, power metal is characterized by a faster, lighter, and more uplifting sound, in contrast with the heaviness and dissonance prevalent in, for example, extreme 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.
Cryptopsy is a Canadian technical death metal band from Montreal, formed in 1988.

They may differ in terms of instrumentation, tempo, song structure, vocal style, lyrics, guitar playing style, drumming style, and so on.
