On April 29th, After School made their much anticipated comeback performance on KBS’s ‘Music Bank’’ with their new mini album title song, ‘Shampoo.’ To mark their comeback, the girls also made a special tap dance execution with performance of ‘Let’s Step Up.’ Unfortunately, the performance didn’t go smoothy, at all.

According to ‘Music Bank,’ After School performed ‘Shampoo’ live but pre-recorded ‘Let’s Step Up. When the girls were already showcasing their powerful tap dancing choreography, part of the glass stage collapsed.

One of the viewers who witnessed the incident said, “After School’s ‘Let’s Step Up’ began with Kahi’s solo, but I was surprised when a part of the stage collapsed.”

Reportedly, the girls wore a metal tap shoes on stage and although the stage was made with a strong glass, it collapsed perhaps due to Kahi’s VERY powerful solo. Good thing, no one was hurt during the incident.

After School’s agency stated, “Members were surprised, but they are taking this as a sign for huge success. Kahi must have been too motivated [to perform].”
