The Sound of Progression consists of 2 producers: Robin van de Wiel and Daniel Wanrooy. They met just about the same time as when they both started getting into producing, which was round the age of 14. Many years past by as the two friends stayed in close contact, always producing, always looking for ways to improve their sound. Then in the year 2001 they decided that it was time to combine their powers and form an alliance, and so Odyssee was created.
In 2002/2003 they got noticed by labels such as Fundamental Recordings (from which Progression was born), Lost Language, Gesture and Black Hole Recordings.
