This tour was awesome! Easily one of my favorite experiences in BA. Matt is extremely knowledgeable about graffiti and has written a book about it. He used to be a reporter at the BBC, and he has an inquisitive perspective. He really knows the street art scene inside and out... and he's actively involved in advocacy and community organization too! We peppered him with questions from everything about the current political situation to drama between graffiti artists, and he was able to answer them with a combination of interesting anecdotes and objective commentary.
