Who is the next big thing ... in the world? MTV Iggy has gathered MTV personalities Matt Pinfield, Sway Calloway and SuChin Pak, as well as Bollywood and TV actress Shenaz Treasury, for today's Best New Band 2011 live-stream concert special at 4 p.m. ET on MTVIggy.com to let you in on the answer.

South Korean girl group 2NE1 -- who were announced as MTV Iggy's Best New Band in the World last month based on fan votes -- will headline the concert, alongside this year's runners-up: Grammy-nominated Venezuelan dance-punk band La Vida Bohème, who released their album Nuestra earlier this year; Jamaican dancehall star Gyptian, who worked with Nicki Minaj on the track "Hold Yuh"; and Malaysian singer/songwriter Yuna.

"MTV Iggy's Best New Band concert symbolizes America opening its doors to pop music from around the world. It's a sign of the times. We live in a global, connected world in which music has no borders. We are going to see that come alive tonight," Nusrat Durrani, senior vice president and general manager of MTV World, told MTV News. "Fans have been lined up outside since midnight. They will experience the magic of being up-close and personal with their idols, who have flown across oceans to come to the USA to perform for them. Fans will also discover new artists they didn't know and bask in a thrilling MTV moment."

The concert will stream on MTVIggy.com, including a global chat with real-time translations in 53 languages run by Ortsbo.com, today at 4 p.m. ET, live from MTV's Times Square studio and the Best Buy Theater in Times Square.

"The term 'world music' does not describe the acts at this event. The Best New Band concert is about pop music ... in all its colorful, loud, chaotic glory -- from K-pop to Jamaican dancehall to indie punk from Latin America," Durrani said. "It reflects the world we now live in -- where the Internet and other factors have created a vast and exciting universe of music accessible to anyone with a connection.

"It brings about amazing opportunities for us to tap into," he added. "For example, tonight you will see Matt Pinfield opine on La Vida Bohème, a band from Venezuela, and people around the world watching the live stream will be introduced to both the band and to Matt Pinfield. You will see Bollywood actress Shenaz connecting the very passionate fans of 2NE1 to the artist. You will see Sway and SuChin Pak introduce all of this music to the world. It's what MTV does very well. It's a very cool show."
