Extreme metal
[6] Extreme metal's sonic excess is characterized by high levels of distortion (also in the vocals – growling, gargling or screaming), less focus on guitar solos and melody, emphasis on technical control, and fast tempos (at times, more than 200 beats per minute).Its thematic transgression can be found in more overt and/or serious references to Satanism and the darker aspects of human existence that are considered out of bounds or distasteful, such as death, suicide and war.[8] This early work by Venom, in combination with bands like Discharge, the Exploited and Amebix, as well as American hardcore punk, brought integral elements into the budding extreme metal landscape at the time.[10] A few months later, Slayer would release their own thrash metal album Show No Mercy, influenced by the sounds of Venom, Judas Priest, Iron Maiden, and Mercyful Fate.[11] When extreme metal band Hellhammer first began making music, it was generally panned by critics, leading to the members forming Celtic Frost in its place, which proved very influential on the progression of the genre.
