Being in London on the day of the music festival is a chance in itself, but realizing that the Thames reveals sandbanks that can be exploited at low tide, it is an opportunity that I had to seize! Luckily, I had my rakes with me because I was coming back from a few days in Wales where I had just met a beach artist counterpart to draw drawings on his beaches with him. What better theme than that of music for this June 21st? So I jump over the barrier to reach this small sandbank on the Southbank side to draw on this mini beach, a treble clef, some notes with their ornaments. Many passers-by will stop to enjoy this spectacle, of a somewhat crazy beach gardener. Show that should not be common for them at this place.
