Michel De Caso was born in 1956 in Toulouse. Up to the age of twenty two, his painting technique was deliberately self-taught, through the systematic study of technical works.

In reaction against the contemporary art of the Sixties and Seventies, De Caso deliberately refused intellectual speculation and threw himself whole-heartedly into the world of colour. Most of his painting from this peroid was done using acrylic resin, appreciated for its fast drying and thus privileging the spontaneity of the gesture. He frequently painted for more than twelve hours a day.

He went to Paris in 1980 with the firm intention of living off his painting but whilst he continued to paint, considering this as his main activity, he initially had to work as an insurance clerk and then as a cultural representative.

He lived in the XIX district for several years and lived a variety of artistic experiences, moving between artist squats to official inaugurations. He took part in several large Parisian art exhibitions: The Autumn Exhibition, Young Painting, French Artists, etc...

His first personal exhibition with more than fifty paintings took place in 1983, in the 'Centre Culturel Mathis' of the City Hall of Paris. Although he was regularly in contact with groups of artists, his atypical character in fact kept him outside any artistic movements.

He settled for some time in Seine-and-Marne, then in the south of Essonne, in the area of Milly-La-Forêt, the city where Jean Cocteau lived. He appreciated the surroundings and particularly the forest of Fontainebleau where he often went to refresh his ideas. It was in this atmosphere that favoured his creation that he created the concept of "Rectoversion" in 1991, while teaching drawing and painting to different people as an independent artist and professor.

He stayed in Ile-de-France for approximately twenty years. During this time he visited and studied the works of art in numerous exhibitions and museums and gradually came to feel the necessity to acquire theorical knowledge. He thus followed several artistic training courses and resumed his studies at 35 at the Visual Arts University of Paris I at the time he was developing "Rectoversion".

His desire to return in the South of France was ever present. Since his teenage years, he had wished to live in the Aude region. In 2000, aged 44, he finally had the opportunity to leave Ile-de-France and move near to Carcassonne.

In the Aude region, the first exhibition of De Caso takes place in August 2001 in the "Maison Gibert" of Lézignan Corbières while in April-May 2003, an exhibition of his "rectoversed" painting is presented in the romanesque abbey of Caunes-Minervois. It is in parallel with this exhibition that he also gives a conference on Rectoversion to the abbey Palate.

On September 20, 2003 in Carcassonne, with the artist Michel Olivier, he realizes the first performance of a "rectoversed" painting carried out in public by two painters. Since 2004, his works are visible permanently in Paris (Galeries Artitudes, ...) and an important exhibition in London happens in October 2005.
