Following up on our series of featured artists from the Tighten UP! podcast volume 4 is our guy ENDBOSS. Not to be confused with this END BOSS, he’s a dubstep producer from Philly getting serious looks for his dirty basslines that reak of Hot Robot Breath. He’s recently teamed up with another Philly producer, Stepkinetic, to form the side project, Silverback. We knew they were up to some damage when they made Nelly Furtado sound dope over dubstep. Mad kudos bars to you two. And with that enjoy the download.
