Most 14-year-olds are focused on school assignments and weekend sport. Shumo AG is preparing to perform in front of tens of thousands of people.
The Australian singer-songwriter, guitarist and multi-instrumentalist has teamed up with Indonesian phenomenon Batas Senja for ‘Iron Veins’, a bilingual collaboration that brings together two artists at vastly different stages of their careers, united by a song that has already resonated across borders.
For Shumo, the collaboration is the latest chapter in a rise that feels remarkably international. Despite still being in high school, he has amassed more than 650,000 social media followers, written over 16 original songs, performed at major events across Asia, and built a particularly strong audience in Indonesia.
That growing connection ultimately led him to Batas Senja, one of Indonesia’s most successful contemporary bands. With millions of monthly listeners and hundreds of millions of streams to their name, the group worked alongside Shumo across several months to reimagine ‘Iron Veins’ for Indonesian audiences while preserving the heart of the original composition.
“The connection with Batas Senja came about because my music started reaching listeners in Indonesia,” Shumo explains. “What I like most is that ‘Iron Veins’ became a bridge between two musical worlds.”
The track itself blends English and Indonesian lyrics, combining emotional ballad writing with melodic rock and indie-folk influences. Built around the idea of emotional armour, it explores the tension between protecting yourself and remaining open to the people around you.
For many artists, an international collaboration of this scale would represent a career milestone. For Shumo AG, it arrives before he’s even finished high school. With plans to perform the song live alongside Batas Senja in Jakarta later this year, ‘Iron Veins’ feels less like a breakthrough moment and more like the beginning of something much bigger.
