Peter Schwind and Christoph Sommer, the producers of the DVDs, studied the first time with Jean-Pierre Barral in 1989. Since that time they had the chance to study his work profoundly as students and as assistants. Their main professional activity is their practice. Aside of that they teach courses at the international program of the Barral Institut and the munich group.
They got the idea to produce professional DVDs while they were in the classroom with Jean-Pierre Barral.
