“In the same way the Indians named their children after a force or animal or element, we named him after a man-made machine that was meant to go up, meant to ascend,” Williams explained, noting he hopes he’s destined for greatness.
He also talked about how he’s adjusted to being the guy in the spotlight, after so many years working behind the scenes as a much sought-after writer and producer who has worked with Jay Z and Gwen Stefani. “I was happy being the guy standing next to the guy,” he said.
Over the weekend, Williams made his Coachella debut, where he was joined onstage throughout his set by friends and past collaborators like Snoop Dogg, Nelly, P Diddy, Tyler the Creator, Busta Rhymes, Diplo and Stefani.
