Performance artist and rapper Zebra Katz hit the fashion scene majorly in 2012 when designer Rick Owens played "Ima Read" on repeat as his catwalk soundtrack, and here he continues his relationship with style by creating an exclusive runway jam for up-and-coming London designer Alex Mattsson, who showed his recent A/W 2013 collection yesterday as part of London Men's Fashion Week. Produced by the Red Bull Catwalk Studio, Katz released the accompanying video for "Pulla Stunt," and in the clip, Katz and his "Ima Read" partner Njena Reddd Foxx breeze into some small town USA, stalking cheesy county fairs while rocking loads of leather Mattsson looks. Check out the video, directed by Grace Ladoja, one of our Video Directors To Watch and styled by Matthew Josephs, one our Stylists To Watch, and see looks from Alex Mattsson's fall/winter 2013 collection below.
