About ‘called!?’

‘called!?’ East KLab’s last original multimedia musical project built on the themes of ‘youth’ and ‘a cappella’!


It was on this unforgettable day that the boys found themselves changed.

In front of them were ordinary high school students like them. There were no flashy costumes or musical instruments.

But the moment they started singing, a surreal harmony filled the air and the crowd went wild.

‘We want to sing like that! We also want to shine!’

High school students captivated by a cappella art aim for the top in the high school’s exclusive a cappella competition, “Aoppella”.

They’re trying to perfect their pitch as the show is about to begin!
