Hi, my name is Heline and I'm a classically trained flute player. I am a professional session musician recording different styles and genres. My latest bigger project was playing in a movie soundtrack (The Curse of Lughus) by multi-award winning composer, Tim Janssens.

Internationally recognized music producer and recording/mixing engineer from London. I was chief engineer at A.I.R. Studios London & Montserrat, now a freelance producer and mixer. I’ve worked with many of the world's finest artists and musicians including Paul McCartney, Rush, Mick Jagger, Mark Knopfler, Corey Hart & John Martyn.

I produce and mix records that have to work everywhere. A stadium, a movie theater, and a pair of AirPods. Most recently that meant co-producing Coldplay's FIFA World Cup 2026 Halftime Show alongside Stargate, and two songs on Paramount's Smurfs Movie soundtrack: "Higher Love" (DJ Khaled, Cardi B) and Tyla's "Everything Goes With Blue." I'm a registered writer at Sony Music Publishing.
