SinNRG aka Duo of Shaylee McMillan and John Walls

Members: Ember, JohnE

SinNRG is an Adelaide hard house and NRG duo comprising UK-born DJ-producer JohnE and Ember, also known as Shay. The project entered a new chapter in August 2026 when Ember joined JohnE behind the decks, pairing his production background with her long connection to Adelaide’s rave floors. Before DJing, Ember was known as a stage dancer and dedicated raver, drawing influence from hard house, hard NRG, freeform, UK hardcore and drum and bass. She won the DJ competition for Ignition’s February 2025 outdoor event, earning a two-hour appearance that included a versus set with JohnE and a solo hour. The pair later performed together at System 6 during a Paul Glazby event. As SinNRG, they focus on driving basslines, euphoric builds and hands-in-the-air hard-dance energy. The reconfigured duo makes its first major back-to-back statement at Hard House Nation in November 2026, supporting Robbie Muir and Technikal at Surge alongside Dramatik, Novakane, Permanence, Nukken and Betterman.
