Indonesia's hijab-wearing, headbanging VOB count some of rock music's biggest stars among their fans, but the all-female heavy metal band faced a tougher battle in winning over their parents.
The diminutive trio behind Voice of Baceprot ("Noisy Voice" in English) have spent years honing their skills at music festivals after forming VOB as young teens in 2014.
It is a long way from the town in West Java province where they grew up, shrugging off a hostile reaction from neighbours and family members to pursue their passion.
Obeying those cultural norms would have compelled the three women to marry right after high school.

The trio's stubborn determination eventually won over their sceptical parents and they moved to the capital Jakarta last year to hone their talents.
'Tough ladies'
The move to the big city comes after their popular 2018 single "School Revolution", which took aim at Indonesia's strict education system.
Much of their songwriting these days now focuses on the role of women and environmental issues.
VOB's critiques of conservative social values resonate across borders and could win them a bigger international audience, said music expert Yuka Dian Narendra.

VOB first attracted international attention when online videos of them pumping out song covers caught the eyes of Nirvana bassist Krist Novoselic, Flea from Red Hot Chili Peppers and Rage Against the Machine guitarist Tom Morello.
The band has played several online concerts since the pandemic shut down most cross-border travel, including the WOW UK Festival in England and the Global Just Recovery Gathering.
They hope their hard-driving tunes will land them a spot at top-tier US music festival Coachella one day, and the chance to collaborate with idols System of a Down.
In the meantime, VOB say they'll keep drawing inspiration from the women in their hometown, where many do back-breaking farm work.
