Robert del Naja is a founding member of the band Massive Attack and remains at the group's core today. Using the tag 3D, he has been active as a graffiti artist since his teenage years. Alongside his crew The Wild Bunch, he is credited as the spiritual leader of the graffiti scene in his native city of Bristol, and his paintings blazed a trail for the urban art movement that was to follow. 3D's painting has represented Massive Attack since the band's inception to the present day, on albums from Blue Lines to 100th Window. He has been involved in no less than four albums for James Lavelle's UNKLE project. The imagery for the UNKLE LP War Stories was featured in the 2007 Lazarides exhibition War Paint. He is also heavily involved with Massive Attack's stadium-show stage visuals produced by United Visual Artists. Del Naja has also co-designed all of Massive Attack's lighting shows with UVA; the shows have been overtly political, dealing with current local and international issues. A regular aspect of 3D's artwork is the adaptation of national flags in the red and black colours associated with the anarchist movement. An exhibition of these flags took place when Massive Attack curated the Meltdown music festival at London's South Bank Centre in 2008. The theme continued at his latest exhibition, Fire Sale, an innovative show of unique screen prints, all of which were sold at a uniform price. The private view for Fire Sale saw Massive Attack play a rare DJ set in Lazarides Rathbone. 3D has backed up the political standpoint in his work with action. Most recently this took the form of Occupied Xmas, an event in support of the Occupy movement, in the "occupied" UBS bank building during Christmas 2011, organised by himself and Radiohead's Thom Yorke.
