Jan Brennenstuhl aka Brenna, born 1988 in the Eastern-part of Berlin, Germany, grew up in between mortal remains of the real socialism and multicultural, subcultural ideas of squatting and creative designing of public space. Influenced by those two contrary mindsets, he started photographing street art in 2006 to document this breaking new, but totally temporary form of urban art.

In 2009, he started, with the aim to establish a daily source for street art and graffiti news, which developed the blog www.urbanartcore.eu, today famous for urban art forms and the latest developments net.

This is his tumblr for mobile photo uploads from the streets of Berlin!
