After spending several years painting musical artists with watercolors, Dan23 opened in 2006 his own gallery in Strasbourg. His first steps as a solo performer making live-paintings then appeared to be more on concerts and music festival stages throughout the world than in his own gallery. In 2013, he decides to quit the stages in order to get more involved into the streets and the urban environment, painting bright portraits, each of them dedicated to a particular song. The « Tour Paris 13 » project in which he got involved, eventually gave him the recognition. Finally, the street-art gallery Mathgoth in Paris offers him the opportunity to make a solo-performance in 2014. A consecration in 2014 which will be present him in events such as Djerbahood, In situ art Festival or la nuit blanche.
