Brothers Kyle and Michael Trewartha constitute Los Angeles-based EDM/dance-pop duo Gray. Initially anonymous, Gray first made an appearance in 2015 with some remixes of paths by Zedd, Kaskade, and Jack port Ü that mixed atmospheric guitars with sharpened, startling synth riffs. The duo delivered their remixes to Skrillex, who brought these to the interest of Zedd, who reposted them, attaining Grey a large number of supporters. 2016 became the duo’s breakout season, as “Starving” (their cooperation with Zedd and vocalist/celebrity Hailee Steinfeld) became an enormous hit throughout the world. This was accompanied by “Adrenaline,” a far more adventurous monitor that was also co-produced by Zedd.
