Katre is interested since his early years in comics, photography and drawing. In early 1990, he discovered the graffiti and his passionate for this practice allowing him to speak out and use all kinds of surfaces.
Between 1998 and 2005, he is involved in associations with the association "Steus" and its activities range from the production of murals and graffiti animation workshops.
Intrigued by empty lots and spaces abandoned, he devotes his mastery of visual art in 2003 at the Molitor swimming pool in Paris. In 2005, he continued his research by signing the book "Out of Time" (ed Colorszoo) gathering about fifty urban artists working in abandoned places. His passion led him to walk the roads in search of these brownfield sites while continuing to paint the walls of Paris. In 2012 he released his second book, "Out of Time 2" (ed Pyramyd) promises to be a new benchmark in the middle of French street art.
