Following the surprise announcement of Brown Eyed Girls' Ga-In releasing a new track titled 'Bad Temper' earlier on December 20th, pictures of her new concept have just been released. Ga-In's track, 'Bad Temper', was produced by the hitmaker combo of Lee Min Soo and Kim Lee Na, who both just recently won the 'Songwriter Award' at the  '2010 Melon Music Awards' for their song 'Nagging', which was sung by IU. The song is said to have an addictive melody, while the lyrics will express more of Ga-In's honest charms, as she sings about telling someone to stop making up lies and acting fake. 'Bad Temper' will be released for online music sites at midnight on December 21st, with possibly a MV for the track coming later in the day.  However, more information has yet to be revealed.
