The brothers

Isaac & Thorald

We left our home country of Australia to follow our wild mother on a journey to reclaim her voice (she was in the original cast of hair and felt a calling back to the theater).

We arrived in NYC, and in 2001 set our sights on a vision to become the biggest band in the world 😎

We embarked on a 15 year music career ( as The Kin ) that went from playing empty dive bars, to playing to millions of people and earning a gold record. We got to play all over the world, and open for the likes of Coldplay, P!NK, Bon Jovi and Rod Stewart.

Yet even with all success, we were left unsatisfied, burned out and falling short of our own expectations the world had put on our voices, and we’d put on ourselves.

We had been chasing our tails. It turns out, We just wanted to be ourselves.

In a pivotal AHA moment, we were simultaneously struck with an idea, WHAT IF we became someones ‘brothers’ and helped them in ways we wished someone had helped us, to walk from inception alongside them, to help nurture and foster their voice to the forefront of their lives,
To help them fall in love with who they are at the core through the sacred medium music, song and singing.

We began our work in 2015, when we created The Songwriter’s Journey, an immersive experience moving someone from inception to sharing themselves in song.

After our first journey, we were hooked.

As of today, we now work with thousands of voices from ALL walks of life through multiple programs and journeys
