Art created regardless of cultural patterns and generally accepted norms, not trained or untrained in the arts by the artist. The term art brut was coined by the French artist Jean Dubuffet. His collection of drawings and sculptures, created by marginal authors, was the impetus for changes in the socio-cultural environment.

Initially, the movement referred to the art created by mentally ill people, but in the future, the concept expanded. The samples of art brut also began to include the work of people with any disabilities, children or prisoners. The creativity of people living in their own world or (and) isolation is distinguished by spontaneity and emotionality, it ignores credibility and pictorial perspective, there is no distinction between the real and the fantastic, as well as there are no categorical requirements for the author. Outsider artists unconsciously create works of art relying on what their own subconscious dictates, regardless of recognition from the artistic environment, market values, traditional models, cultural canons.

Authors often do not have an understanding that they are creating a work of art, as it is outside their sphere of consciousness. This means that art brut does not imitate official art and does not enter into discourse with it, and is not a manifestation of rebellion. For outsider artists, art is a way to articulate their feelings and emotions about life and attitude.

Belarusian artist Mikhail Senkov, known under the pseudonym A.R.Ch., works in the author’s technique “academic art brut”. The work of Mikhail literally brought back the theme of death for Belarusian art. It captures life in the world of death, shows another universe, speaks of destruction. In his paintings, complex relationships are established between the executioner and the victim, in which the spectator participates.

Gallery "Labyrinth" in Minsk presented the exhibition "The Art of Outsider" (2009), which exhibited the work of twelve residents of psycho-neurological boarding school No. 2 in Minsk. Among these people are former artists, architects, military men, as well as childhood invalids. The works are the practice of art therapy, and therefore a way to communicate with yourself at the level of primary emotions, as well as the search for your significance.

Outsider art is often poor in form, instead reflecting a strong inner creative impulse dictated by the inner experience and spontaneity of the artist. Art brut depicts a strange, closed, wary, dark and, of course, not the most hospitable world.
