Katre became interested in comics, photography and drawing from a young age. In the early 1990s, he discovered graffiti and became passionate
for this practice allowing him to express himself outside and to exploit all kinds of surfaces. Between 1998 and 2005, he got involved in associations with the association "Steus" and his activities oscillated between the creation of frescoes and the animation of graffiti workshops.
Intrigued by vacant lots and abandoned spaces, he devoted his mastery of plastic art in 2003 to the Molitor swimming pool in Paris. In 2005, he continued his research by signing the book "Hors du temps" (ed Colorszoo) bringing together some fifty urban artists working in disused places. His passion led him to roam the roads in search of these brownfields while continuing to paint the Parisian walls. In 2012 he released a second book: "Hors du temps 2" (ed Pyramyd) which promises to be a new reference in the French street art community.
Travel and meetings allow him to join several collectives and to regularly participate in festivals around the world (China, Chile, Australia, Spain, Italy, etc.).
