The other new tracks on the EP were Tunde Adebimpe's "Pray For Rain", Martina Topley-Bird's "Psyche" and Guy Garvey's "Bulletproof Love". The latter two tracks appear as remixes of the album versions. The fifth album was released on 12 November 2009, called Heligoland, after the German archipelago of Heligoland, after a previous project called "Weather Underground" was abandoned. Del Naja said "I think it's got definitely a more organic feel". The opening track, "Pray For Rain" featured guest vocals of TV on the Radio's Tunde Adebimpe, and Damon Albarn and Mazzy Star frontwoman Hope Sandoval also provide guest vocals on the album.
