Massive Attack are back. And right now, at a time when anodyne celebrity obsessions and endless Popstars juggernauts are monopolising the cultural landscape, we need Britain's most influential band more than ever. Massive Attack have consistently pushed the boundaries of both their own sound - twisting their soundsytem roots into the complex, insistent guitar layers of Mezzanine - and constantly surprised with their inspired collaborations and groundbreaking art direction.
