Although half of the aforementioned bands (specifically including Metallica, Megadeth, Slayer, Dark Angel and Suicidal Tendencies) were technically not from the Bay Area, they are often credited for popularizing and contributing to the thrash metal scene in Northern California during the 1980s by frequently playing shows there, especially early in their careers and/or before they received their first record deal. East Coast thrash metal: Centered in New York City, the East Coast's thrash metal tended to display a sound that incorporated a strong hardcore punk influence.
