We did a private walking Tour with Demian last Monday, 10/6/13 and had a marvelous experience. His evident passion-to me the most essental component of any art guide- is infectious and his knowledge is extensive. Having been a tagger when younger, he knows whats up and what artists are and coming. He is a bright, well spoken Brit, now a Paris resident, who can discuss in depth the histroy and genesis of urban and street art. We are older(62yrs) but were wtih our 30 yr old daughter, have traveled in many places and done many graffiti/street art tours, and this was definitely one of the best-we all agreed. There is so much street art to see in Paris,so don't expect to cover even close to all that is there, but Demian will get you started and you can then look up, and all around on your own having a bit of background to follow this addictive art form. You won't be disappointed. We highly recommendt o anyone who loves graffiti and street art, or just wants to know why all the strange tiles and painting on Paris walls.
