When Glen E. Friedman started shooting in the ’80s he drew no boundaries between the seemingly disparate cultures of skateboarding, punk and hip hop. Friedman saw an attitude and an energy that united them, and he documented it with respect and dedication.

Now, twenty years on, his work is a historic testament to a unique era and the off-the-wall characters – some of whom are no longer with us – that continue to inspire and define popular culture.

We caught up with him when he was in London for his exhibition My Rules – an immersive selection of photography from his new book of the same name – and got to the bottom of his in-the-thick-of-it approach.

Glen Friedman: My Rules, the exhibition, runs at 14 Henrietta St, Covent Garden from November 21st – January 18th.

The book, My Rules, is published by Rizzoli priced at £35.00.
