Guillaume Costes Gallovalla's style can be traced back to his parent's love for music. In 2013, the Agen, France native adopted the alias Rusty Hook, centred around a divergent sound that draws upon alternative rock, US hip-hop, and French electronic music. With his tracks at a current standing of over 17 million streams, Rusty Hook has earned the respect and praise of tastemakers like Skrillex, What So Not, Madeon, Porter Robinson, Ekali and more. His portfolio also includes being part of the Slow Hours group in France.
