Isak has killer vocals!  The star, who is currrently juggling Arirang DJ work and acting in a play, tweeted a clip of herself belting out a tune in her play “Spring Awakening“.  Her Midday Break is over when the 20 – something actress portrays a 14 year-old in the stage production about discovering sexual identity.  The following message accompanied the video uploaded by a fan

“KEWL~! lol for those of u who wanna see me sing the Korean version of Blue Wind from the Musical Spring Awakening! here”

What did you think of her performance?  Did she master all the emotions of the piece entitled “Don’t Do Sadness/ Blue Wind”?

“Spring Awakening” will run until September 4th 2011 at Seoul’s Du San Art Center.
