Photographer Al B. For has a keenly honed sense for where fun is happening; in a given month, he’s equally likely to be snapping frames at an art-gallery reception, a restaurant opening, a game at the Wells Fargo Center or a posh nightclub. The last couple weeks have seen Al crisscrossing Old City to document a diverse nightlife scene: The Philly Fashion Expo’s preview mixer at Fire & Ice, for instance, drew a crowd of style mavens both young and seasoned. Meanwhile, on the 11th floor of the Hotel Monaco, the Stratus Rooftop Lounge celebrated the half-year mark with a Christmas in July party. Um—we’re not gonna ask what’s in the box.
