A Brief History Of Graffiti

An interesting voyage, albeit in condensed form, through the history of graffiti fromcrude marks left by soldiers in Germany right up to modern-day stuff from France's Blek Le Rat.
The legendary LEE Quinones has a great segment and shows us into his studio where there is a brilliant mural featuring some of his contemporaries such as Futura, Rammellzee, Fab 5 Freddy and Lady Pink.
This could so easily be turned into another 'stuffed shirt', BBC4, condescending view of the street art world but our guide (Professor Richard Clay)is ultimately enthusiastic and open-minded about the subject which makes the whole experience that much more entertaining.

Word of warning, as it's on iPlayer it is only available for a limited time - in this case until 24th September 2015. Plus if viewing from outside the UK there may be restrictions.
