Demi Lovato harkened back to her "Hot Topic roots" on Tuesday night during a guest DJ spot at Emo Nite L.A.  The sound went out but she kept on rocking, a cappella style, with a fierce version of Paramore's "Misery Business." 



"Ready, we're going to sing it again. Technical difficulties," Lovato told the audience crushed in around her, which included Post Malone and Sirah. "We're going to f--king rock this s--t."
