While You Were Sleeping was started by Roger Gastman when he was just 19. At the time, Gastman was running a graffiti supply company and his magazine could easily be described as a sort of Big Brother for the graffiti set. Of course, that is reductive, but you should get the idea. Gastman's gone on to become a major force in the art world, curating big shows and producing comprehensive history books. If you missed the early part of his career, your chance is now.
The Worst of While You Were Sleeping compiles the best of what was a flat out brilliant publication.
