Unfortunately, the band manager and bass player died, while many other band members are missing or injured, the almost unscathed lead singer told fans on Sunday.

"Please pray that we can find Andi, Herman and Ujang and my wife," Riefian Fajarsyah said.

It's not clear how many concertgoers were killed or injured in the tsunami.

Indonesian officials said the tsunami was triggered by the eruption of the Anak Krakatoa volcano, which likely caused underwater landslides. Unfortunately, there was no warning a tsunami would strike, according to The Guardian.
