Glenn Brown, painter and sculptor: 'Sculpture has to operate in its own right - it cannot be slavish to its sources'

Glenn Brown has been in his studio near Old Street roundabout in east London for five years. A large modern space with top lighting, it is filled with signs of industriousness. In the hallway are armatures for the new sculptures he is working on and a suite of soon-to-be-shown drawings are ranged on the wall.
