If some painter's actions are underlying their aesthetic and conceptual intentions, they are also determined by practical and material factors. The particular and recurring gestures, which generate styles, palettes and subsequently corpus of works, are often the result of a succession of habits, tics even errors. It is in this perspective that Mathieu Lévesque's most recent research focuses on this ambiguity between the painter's know-how and laissez-faire. While it is common within the practice of painting to repaint rejected paintings, Mathieu Lévesque dwells on the radicality of this precise action which for him underlines the limits of the frame and accentuates materiality.
