EMINEM took over the EMA's receiving the Icon Award and performing "Berzerk" and "Rap God" and we are starting to think it is the way "Berzerk" is performed that looks like he is lip syncing.
Not as big as he once was, but still dominating.....
No backing track is used during EM's performance of "Rap God" and you can clearly him rap. "Berzerk"'s vocals were more clear than his SNL performance but the backing track is still prominent.-DocFB
Diagnosis: Is there any way for the band to perform "Berzerk" without the backing track?
