The origins of thrash metal are generally traced to the late 1970s and early 1980s, when a number of bands began incorporating the sound of the New Wave of British Heavy Metal, creating a new genre and developing into a separate movement from punk rock and hardcore. This genre is more aggressive compared to its relative, speed metal, and can be seen in part to be a reaction to the lighter, more widely acceptable sounds and themes of glam metal.
Thrash metal generally features fast tempos, low-registers, complex guitar riffs, high-register guitar solos, double bass drumming, and aggressive vocals.
Most thrash guitar solos are played at high speed, as they are usually characterized by shredding, and use techniques such as sweep picking, legato phrasing, alternate picking, string skipping, and two-hand tapping. Thrash lead guitarists are influenced by the New Wave of British Heavy Metal movement.
