Group 2NE1 will hold the world's first-ever 4D music video showcase. The group will hold their 4D music video showcase on September 18th at the Yong San CGV. YG Entertainment said, "2NE1 will be the first ever to show the music videos for its first album's three title tracks, 'Can't Nobody', 'Go Away' and 'Clap Your Hands' at CGV 4D PLEX on this day." (*For those of you who aren't familiar with 4D technology, it's basically like an upgraded version of 3D. If there's a snow storm in the movie, the theaters actual temperature drops, and it becomes windy. If there is an earthquake, the seats shake. It provides the audience with an experience as if they are inside the film itself. Apparently, you can even smell things from 4D films!) Meanwhile, 2NE1 launched its official promotional activities on the 12th on SBS's "Inkigayo"
