About us (официальный сайт):

Thomas Bergersen: I was born in Trondheim, Norway and spent about 22 of my years there. Interesting place, Norway is. But I maintain that I was born in the wrong country, because the first word that came out of my mouth was a rather mangled permutation of "America", and I was born on the 4th of July. I decided early on that I wanted to express myself regardless of repercussions, and so I rebelled quite a lot. Against my parents, teachers, you name it. I couldn't stand authority and that was probably the reason why I started composing music in the first place. It was the perfect way for me to disobey rules and do everything like Frank Sinatra, "My way". I was 6 years old and my piano teacher did not share that view. It didn't last very long. I sure showed her!%#! or maybe not.. then again I remember she looked like she was about 90 at the time and if she's still alive she must be at least 250! Soo.. what else.. oh yeah.. "F" in maths ... Am I a bad person for not remembering her name? I was never good with names either. Maybe she's looking down from a litte cloud above, hands covering her ears and cringing as she listens to me butcher Bach's 1st inversion in C Major for the N'th time. Or maybe I make her proud?

Nick Phoenix: I was born in London England, but grew up in New Haven CT, where I learned how to fight off stray dogs and unfriendly classmates. I attended Hopkins Grammar and UCONN. I studied classical piano for ten years and have played in rock bands since I was 12. While at UCONN, my brother loaned me $4000 so I could start a home studio. And that began my journey into recording and sound. I have been producing "Quantum Leap" virtual instruments for EAST WEST since 1997, when I produced my first title. Since then I have produced and co-produced many titles including EWQL Symphonic Orchestra, EWQL Symphonic Choirs, Stormdrum 1 and 2, RA, Silk, Gypsy, Pianos, Hollywood Strings, Hollywood Brass, Spaces, Ministry Of Rock 1 and 2 and others. Its been an interesting ride. My journey creating sounds has always been fueled by composing music and striving to improve the sound of my compositions. In 1997, I also began composing music for film trailers. Over the years I have either scored or placed music in over 1000 major motion picture trailers. I have also scored TV shows and worked on films with Hans Zimmer. Living in Los Angeles gives me amazing opportunities to work with talented artists and I recently did a project with Mickey Hart of the Grateful Dead. Thomas and I formed Two Steps in 2006 and I believe we have a great partnership. Working with someone as talented as Thomas inspires me to improve.
