Beyond Code

Soul on Wheels

Movement is life, and it is even better on wheels. Soul on Wheels is my rollerblading and cycling channel: streets, spots, nature, and the freedom you feel when nothing else matters.

Every ride is a story, filmed like a memory and cut like a beat. On the web I am soulgarden, and on the road this project lives as Soul on Wheels.
