creative but clean mixes and unique production
With 20 yrs experience in studio sessions, I bring nuanced, emotive performances that make you FEEL things.
I've composed, produced and played on everything from indie pop songs to orchestral Disney film scores. My music has been featured on NPR, in The New York Times and has been lauded by David Byrne of The Talking Heads, and I've scored multiple films from Cannes-featured dark shorts to romantic comedies starring Hugh Grant.
I don't stop until your song is perfect, Songwriting is a gritty sport. You need to throw jabs (write) to improve. Not only do I write everyday, but I document my progress, and have made my coaching available on YouTube. I am optimistic, can work with any voice range, and I can make you a better songwriter with our free consultation alone.
