Radical Son is the creative moniker of David Leha, an artist from the Kamilaroi nation of Australia and the South Pacific nation of Tonga. His voice carries the compelling story of his turbulent past, restoration through culture and ever-deepening connection to Country, which has been captured in two critically-acclaimed albums: Cause ‘N Affect (2014) and Bilambiyal (2024).

Radical Son will be joined at UKARIA by two of his bandmates for an intimate performance of his ARIA Award-nominated album Bilambiyal (The Learning). Created in collaboration with artists including Emma Donovan, Frank Yamma, Marcus Longfoot and Jida Gulpilil, Bilambiyal weaves spoken word with potent songs that speak to resilience, identity and cultural strength.
