Mark Ambor Unleashes “Who Knows,” A Viral Tour Favorite Poised for Summer Domination


Pop breakout Mark Ambor shares fan-favorite single “Who Knows,” already a tour standout.
Mark Ambor releases “Who Knows,” a song fans across Europe already know by heart. First teased live on his sold-out Rockwood Tour, the track has taken on a life of its own, with concertgoers singing it back to him before its official release. Now, the viral moment is matched with a music video that brings the energy to screens everywhere.
Written and co-produced by Ambor with hitmakers Noel Zancanella, Ian Fitchuk, and Ammo, “Who Knows” is a bright, forward-driving anthem that blends feel-good pop with subtle emotional undercurrents. Its breezy confidence and relatable message make it tailor-made for summer.
“It’s one of my favorite songs I’ve written in the past few months,” Mark shares. “I saw how people connected with it live, and I figured I should just put it out.”
His Rockwood Tour has seen the New Yorker sell out shows in cities like London, Paris, and Dublin, often adding surprise performances after the main events to even larger crowds. The demand has only grown as his momentum continues to build.
With over 1 billion streams for “Belong Together,” and widespread acclaim for his debut album Rockwood, Mark Ambor is not just building hype—he’s delivering on it.
