In a previous statement Gwon said, "It's been two-and-a-half years since my last big concert in NYC, when the Ordinary Days cast album was released. I'm thrilled to be back, and can't think of a better way to celebrate than by stuffing this evening full of the great new friends and music I've made over the past few years. There'll be some old favorite songs and people, too, and, of course, a surprise or two along the way!"
