WK has proved himself to be one of the truly original and innovative street artists in his ability to marry the movement of the street to the dynamism imbued in his work. WK Act 4 explores 25 years of WK s work on the street, producing everything from small scale stencil work and throw ups to huge wall paintings and murals - featuring graffiti graphics, illustration, art objects and supplies - all beautifully complementing the perpetual motion of urban life. The book features an extensive collection of some of the artist's most famous works including his 17-painting installation at the Colette Gallery in Paris, the iconic decorations of building facades in downtown Manhattan and Project Brave, a moving 9/11 memorial at the World Trade Centre. Complete with an in-depth introduction and biography with contributions from several contemporaries, the book presents a fascinating journey into the world of WK. "WK Interact's iconic black and white street art - human figures engaged in some type of extreme motion or emotion, running, jumping, screaming, struggling to escape - has forever pierced our memory of the Lower East Side and SOHO streets." Isabel Kirsch continues to write in the introduction, "the impermanent, multi-dimensional surfaces of the ever-hustling and bustling inner city are the ideal backdrop to bring his images to life."
