See the hidden World Trade Center art gallery Spotify tapped for its headquarters

The art found on the 69th floor of 4 World Trade Center is not the kind you would expect to see in the financial district.

Larry Silverstein, founder of Silverstein Properties, the developer of 4WTC and many of buildings in the area, is a fan and proprietor of the arts and has worked to bring art to all of the newly developed buildings in the area. But even Robert Marcucci, Silverstein Properties' art consultant and Silverstein Properties Chief Marketing Officer, Dara McQuillan were nervous about approaching Silverstein with the idea of a street art studio and gallery in the building.

They recalled bringing Silverstein and his wife down from a party to show them their ideas, hoping that the celebration upstairs had put him in a good mood.

Luckily for Marcucci and McQuillan, Silverstein was thrilled about the out-of-the-box approach to bringing more art to the area.

"I think it is a positive change," said Silverstein. "We are living in a world that is so rapidly changing. [The art] is unusual and totally new and different but it's something that will soon be grasped by the commercial community.

Spotify, who will move from the Flatiron District to 4WTC plans to keep the art and incorporate it into their office design.
