In 1994, independently from each other, Moses and Taps began to shape public space and make it their own. They focused on their mutual medium of choice: spray paint and trains. For them, these trains doubled as huge steel canvases and by the early 2000s, they had painted several thousands of trains throughout Europe. In 2007, they met and founded the artist collective TOPSPRAYER™. Their first project was an ambitious one: to paint 1,000 trains in 1,000 days, using each other’s names and operating under both the rigid rules of graffiti and those of the authorities. This led to their first book “INTERNATIONAL TOPSPRAYER™“, the most commercially successful graffiti book to date. Today, Taps & Moses are world-renowned and celebrated for their balancing act between the consistent development of graffiti and their conceptual strength. Beyond being leaders of a generation of graffiti writers, their influence reaches areas such as graphic design, visual arts, advertising, fashion and more.
