This unconventional exhibition, which brought together 18 musicians in South Korea, organized by Cramit Studio, is an exhibition project designed to share the experience of a different way to approach 'music' as a 'works' of musicians. The title of the exhibition, "B Folder," is short for Black Folder, meaning that artists with each unique colour will gather in one place and become black. The exhibition went on for 10 days attracting 12 hundred visitors. We planned a concert with three musicians on the last day of the exhibition, and more than 200 people came there.
