Just a few weeks after their collaboration with Cope2 and A'mare Stoudemire for a launch party celebrating a line of custom skateboards, W Hotels continues to take over the summer with a new event series called W Gangs Of New York. The summer concert series is inspired by the classic cult film The Warriors, and will reportedly feature "the city’s finest and most credible record labels" in an ongoing soundclash battle that will "highlight why they are the ultimate (musical) Gang of New York." The events will all be free to the public (with an RSVP), and the first one kicks off tonight at the W New York - Union Square with a performance from the legendary Grandmaster Flash. Check out the flyer above.
