We reported a few months ago that Nassun, an underground hip hop artist, teamed up with producers E-Tribe and 4minute's HyunA for the track 'Outlaw in the Wild'. Recently Nassun teamed up again with another idol star but this time with MBLAQ's G.O. The song is titled 'O-IWI-O', and a 30 second music video teaser for it has just been released. Check it out below. Thanks to everyone who sent in the tip.
