Here's a powerful collaboration: Missy Elliott performing at the first US recording of M! Countdown on August 25th at the KCON 2013.Missy Elliott will be one of many big-named celebrities performing throughout KCON: G-Dragon, EXO, f(x), Teen Top, 2AM, Dynamic Duo, Super Junior M's Henry, and Yoo Seung-woo.The American rapper's appearance may have something to do with an announcement G-Dragon had made back in June. G-Dragon had said his second solo album -- set for an August 18th release - will feature Missy Eliott. It hasn't been confirmed whether the Grammy-award winning rapper will perform with G-Dragon or not. The big k-pop convention/concert, KCON 2013, will be held from August 24-25th at the Los Angeles Memorial Sports Arena.
