The Writing on the Wall (1986)

"In this half-hour documentary, Producer Sandra King provides an intimate portrait of a public phenomenon: Graffiti. Over an 18 month period, King and her crew followed the teenage members of a graffiti 'crew,' Vandals on the Street, as they painted and rapped and moved through the streets of downtown Newark. What emerges is a unique glimpse behind the 'tags' at the kind of inner city kids who write on walls, but who also make art; who create out of wedlock children, but who also form binding relationships; who drop out of school and never read a book, but who create their own brand of poetry through the medium of 'rap.'

Unfortunately the movie The Writing on the Wall is not yet available on HBO Max.
