Painting is above all an inner journey.

In today’s world, this definition is often forgotten.

Yet this is what distinguishes the artist from the maker of image as a product. The various external constraints related to the profession sometimes create obstacles to this journey by disturbing the flow of true creative energy.

Also, just like the musician, the filmmaker or the dancer, the painter cannot really evolve without mastering certain technical bases. The artistic style should not be the result of a forced research but rather something that develops naturally through the gradual questioning of previously mastered techniques. This process then becomes more creative and takes the personal pictorial language to another level. From there starts the most important quest, the perfect symbiosis between our emotions, our outlook on the world and our ability to express them authentically with less possible filters.

My teaching method reflects this concept where technique is ultimately put at the service of candor and feeling.

Nature has been my favorite subject for 25 years and I will never get tired of it. An inexhaustible source of inspiration that spans the ages and transcends all schools of painting.

All these years of observing the landscape and painting it have made me realize so much about its dizzying complexity and developed in me the desire to express more than just its inherent beauty.

As Cézanne said: Painting from nature is not copying the objective, it is realizing our sensations.

About The Artist

Artwork by Marc Grandbois

Residing in Anse-St-Jean in Quebec, Marc Grandbois was introduced to painting at a very young age alongside his mother, herself an artist-painter. He completed his Fine Arts at Concordia University in 1991 and quickly gained a certain notoriety as a watercolor painter between 1992 and 2002. Along with his production, he taught painting and drawing and participated in numerous symposiums around the province.

 Tired of the financial uncertainty often associated with the life of an artist, he put aside his easel and brushes for a good ten years, contenting himself with painting on occasion and accepting a few contracts. In 2010, he left Mauricie for Saguenay. The exceptional beauty of the landscape and the unique environment of the fjord motivate this decision and will be the trigger for a return to his first passion; the painting. The Nordic landscape has always been his primary source of inspiration. His work is characterized by the priority given to the atmosphere, the casual but fair brushwork and the richness of colors. His palette, sometimes subtle, sometimes wild, adjusts according to the moods he wants to create. ”I firmly believe that figurative art, especially landscape, remains very current if it transcends the narrative and becomes in a way a basis for experimenting with gestures, color and light”. Signatory member of the IAF, we find the works of Marc Grandbois in several galleries and public / private collections in Canada and abroad.
