The band were performing in a packed marquee when the wave hit.
Footage posted online shows the moment a tsunami wave struck the tent where top Indonesian pop group Seventeen were performing, sweeping members off-stage.
Lead vocalist Riefian Fajarsyah, in an emotional video posted on Instagram, has said that the band’s road manager and bassist have been killed, and three other band members—along with his wife—were missing.
The group was performing in a packed marquee in the Tanjung Lesung beach resort on the western tip of Java when the tsunami hit.
The video shows them performing in the tent, when a wall of water crashed over the back of the stage, sweeping away band members and crashing into people dancing in front.
