I called into the Jerwood Space last week, to visit the new 'Drawing Prize 2011' exhibition. Although I'd debate the definitions applied to a few works (video installations etc), there's a fantastic range of interpretations to the seductively simple act of applying graphite to paper.
This year's overall was Gary Lawrence, with his large, highly detailed piece, 'Homage to Anonymous'.
It's worth a trip in itself, but it's also minutes from Tate Modern, and access is free. Pop in.
