Former Fly To The Sky singer Brian Joo released his digital single a few days ago and officially launched his comeback with live promotions. The singer returns to the stage and wraps up a successful weekend of live performances on SBS Inkigayo with his track In My Head. Brian's track isn't really an original and is actually a cover of American artist Jason Derulo's track with the same name; but of course that doesn't mean the song isn't good. In fact, Brian's k-pop spin to the track probably boosted Derulo's exposure to the Korean community, much like last year when David Craig chose singer Wheesung to cover his song Insomnia. Brian's performance is definitely a fun to watch as you can tell that he truly pours his emotions into the song. It's also great to see him show off his English accent near the end of the song. Watch as Brian gets in your head with this addictive track. http://www.youtube.com/watch?v=-gAePWk9izI
