Caleb Neelon is an artist and writer based in Cambridge, Massachusetts.

As a thirteen-year-old in February of 1990, Caleb Neelon visited family friends in small-town Germany with his mother and took a side trip to Berlin. For Neelon, the sight of the newly opened Berlin Wall, covered in graffiti and murals was a revelation.  By the mid 1990s, Neelon was immersed in the global graffiti scene under the name SONIK. He traveled constantly and developed a vivid, homespun, and raw style of mixed media painting. He freely crossed boundaries between graffiti, murals, and what would soon be referred to as street art.  As a teenager, he began to write in-depth articles for graffiti fanzines, documenting the art, artists, and history of his global community.  

Today, Caleb Neelon's murals and artworks can be seen in city streets and exhibitions throughout the world.  Neelon's broad range of recent activity includes studio artwork, cultural diplomacy projects through the U.S. State Department; curatorial work at museums, projects bringing artwork to hospitals, documentary film production, and painting for fun in the street.  Neelon has authored or collaborated on over two dozen books, of which the biggest pain in the ass by a wide margin was the landmark 2011 HarperCollins release The History of American Graffiti, co-authored with Roger Gastman. He is currently working on something cool and spending time with his four-year-old daughter.
