When you walk into a gallery, particularly one in Mayfair, you don’t expect to see such a hive of activity with paint being dripped, sets hammered, installations constructed, in other words a gallery being used as a working studio. For this is what is happening to the Lazinc Gallery for the coming weeks where some 25 contemporary urban artists from around the world will be transforming the place and offering the chance for visitors to watch the process of art in the making.
