Martina Topley Bird and Robert “3D” Del Naja (Massive Attack) have collaborated on a limited run of MTB’s previously digital only ‘Pure Heart' EP release. The 4 track EP, including a vinyl exclusive track “Collide”, is now presented with 3D’s artwork, released via his Battle Box imprint. Each 12” sleeve will be individually hand silk screen printed using 2 colours on 350gsm reverse board to create a collectable and unique piece of art. Martina Topley-Bird's distinctly creative relationship with Robert Del Naja, the artist also known as 3D can be documented through a long history with Massive Attack and rooted in those very first visits to Bristol that lead to Topley-Bird appearing on Massive Attack’s 2010 album Heligoland with tracks "Psyche" and "Babel". Commenting on the significance of the collaborative project and artwork release, Del Naja; "We are proud to be releasing this special 12 inch MTB X RDN edition of the Pure Heart ep on the Battle Box label. It's a symbolic way to celebrate our first musical collaboration since Heligoland.” Battle Box is Robert "3D" Del Naja’s limited edition vinyl imprint which has released collaborations with Guy Garvey, Tunde Adebimpe, Jupiter, James Massiah and Noel Gallagher.
