We meet on an afternoon at Julien's in the heart of the 11th arrondissement of Paris. The weather is good, we have prepared a simple outfit for him, without too many colors, which strangely suits him very well. We've known each other for over 5 years, when he did his first concerts in front of less than 100 people he always wore his pair of socks and his white Walk t-shirt with the purple and green oval logo. A classic of the brand. Since then the number of people at his concerts has increased, and so has the number of colors on his outfits. But our relationship remains unchanged.
