Vocalists Yohan "Doni" Saputro and Riefian "Ifan" Fajarsyah, and bassist M. Awal "Bani" Purbani joined the band at a later date.
The group was performing in a tent at the Tanjung Lesung resort on 22 December 2018 when the 2018 Sunda Strait tsunami, the result of an eruption from Anak Krakatau, struck the stage from behind, killing almost all the members of the band.
The band was formed by Harjanto, Sikumbang, Angga, and Darmawan, students who attended a private high school in Yogyakarta.
The difference in vocal characteristics between Saputro and Fajarsyah ushered in a change in Seventeen's genre, moving their style from rock to a more pop sound.
Seventeen's third album, Lelaki Hebat ("Great Man"), was released in 2008; illustrating thea drastic change from rock to pop.
[3] In 2011, the band released their fourth album, Dunia yang Indah ("The Beautiful World"), introducing the hit single "Jaga Slalu Hatimu" ("Always Keep Your Heart").
In 2013, due to differences in music vision, replacement guitarist Yudhi Rus Harjanto left the band justas the fifth album Sang Juara ("The Champion") was to be released.
Seventeen was performing at the PLN Family Gathering in Tanjung Lesung, Pandeglang, Banten, when an eruption from Anak Krakatau caused a tsunami that abruptly struck the stage from behind.
Crew member Rukmana "Ujang" Rustam and vocalist Fajarsyah's wife, actress and TV personality Dylan Sahara, were also killed in the tsunami.
