A was an influential Russian painter and art theorist. He is credited with painting the first purely abstract works. Apparently, he suffered from B, a neurological condition which causes your senses to cross paths with each other. It may cause you to perceive one sensory input in through many senses or join data like dates and names with some sensory inputs. A recalled hearing a strange hissing noise when mixing colors in his paint box as a child, and later became an accomplished cello player, which he said represented one of the deepest blues of all instruments. He conceived three plays combining the arts of painting, music, theatre and dance into Wagnerian total works of art or Gesamtkunstwerks, which were designed to unify all the senses.
Recently a song C by the singer D also raised some speculations about the singer having the same condition due to the lyrics of the song and an interview.
