As expressed earlier, Big Bang concluded promotions for their repackaged album on today's episode of Music Core with their final performance of 'Stupid Liar' on the show. "Stupid Liar" was one of two title tracks for their repackaged album, and were co-produced by G-Dragon and Teddy. It delivered a catchy, electronic rhythm with a unique modern rock feel and became another trend in the K-pop industry as it charted at the top of various music ranking charts after release. Due to Big Bang's impending Japanese tour scheduled for May through June, YG Entertainment had earmarked a short promotional period which will end this weekend. So check out their goodbye stage below!
