What artist do you think I should listen to that i probably haven't heard of.

I listen to everything from hip hop to black metal (some of my favorites include: Kendrick Lamar, Dead Kennedys, Fall of Efrafa, Botanist, Burzum, Primus, Gorillaz, Clarence Clarity) and i would really like to find some new artists that i might like p.s. with punk rock, the more hardcore the better via http://wapmaxi.com
