MTV has released the trailer for its upcoming documentary “No Cameras Allowed.”

“No Cameras Allowed” follows James Marcus Haney’s journey of breaking into music festivals and getting into circles with names like Mumford & Sons and Jay Z.

“I was no longer an outsider looking in,” he says in the trailer.

The film highlights Haney’s love of photography and filmmaking, and the passion that drives him to do nearly anything to see his favorite bands perform.  Using his camera as a prop to access festivals, Haney comes away from events with intimate footage that impresses his famous subjects.

Said Mumford & Sons bassist Ted Dwane in a statement, “he is so hungry for is what makes his images so unique and compelling and the force that propels this behavior is deep within him and pure.”

“No Cameras Allowed” premieres August 29 on MTV.
