About Paradise Circus

"Four Walls" / "Paradise Circus" is a collaboration between British electronic music artists Massive Attack and Burial. The single was first released as a limited vinyl edition on 17 October 2011, with pre-orders from 10 October 2011. It consists of Burial mixes of Massive Attack's previously unreleased track "Four Walls", and of "Paradise Circus", which was featured in their 2010 album Heligoland. Both songs contain vocals, and lyrical contributions, by Hope Sandoval of Mazzy Star.

In late 2009, Daddy G of Massive Attack appeared to suggest in an interview with Clash that there would be an equivalent remix album of Heligoland by Burial, yet various comments made afterwards cast major doubt on the prospect ever being more than an idle whim. In May 2010, Massive Attack's Robert Del Naja told Q magazine that, "It's happening, but we can't talk about it. (Burial)'s very private and paranoid about it.
