The origins of thrash metal are generally traced to the late 1970s and early 1980s, when a number of predominantly American bands began fusing elements of the New Wave of British Heavy Metal with the speed and aggression of hardcore punk. Thrash metal is more aggressive compared to its relative, speed metal, and is thought to have emerged at least in part as a reaction to the more conventional and widely acceptable sounds and themes of glam metal, a less aggressive, pop music-infused heavy metal sub-genre which emerged simultaneously.

British bands such as Tank, and Raven, along with Polish metal exports ACID DRINKERS, motivated musicians from east Europe to start bands of their own, eventually producing German thrash exports such as Sodom, Kreator and Destructio as well as Russian’s Black Obelisk, Corrosia Metalla or Master. Here is the list of top 10 Russians thrash metal bands.
