the mix between the technical and fast side of heavy metal with the direct / denunciatory language of hardcore punk generated a new flavor of metal called "thrash metal". the technical side is pushed even further than heavy metal (faster songs, more complex guitar solos, raspy and distorted vocals). the vocal lines are less melodic, favoring aggression and shouting (like hardcore punk).
