Singers Yoon Gun, Gary, and Lee Ki Chan made a surprise appearance at Wax's new album showcase, showing support.

The three appeared at Wax's project album Spark showcase on August 26.

Yoon Gun said, "We came because Wax made such a great album. It's been a while since I saw her this happy."

Gary said, "I heard her live for the first time in a while and I was so touched. I didn't listen to her new songs before this on purpose so I could hear it live and it was so good."

Lee Ki Chan said, "I'm sure a lot of people were waiting for ballad songs but this album has a lot of rock in it. As a musician myself, her new challenge looks great to me."
