Rob Tufnell Gallery in London has an exhibition centred around Gaudier (of Savage Messiah) "with contributions from... Sophie and Henri Gaudier-Brezska, Ken Russell, Derek Jarman, Ezra Pound, Christopher Logue, Derek Boshier [Pop Goes the Easel]". I hope to go soon, so more details then. It is on to 28 May 2011.
