Blackfield is a collaborative music project by the English musician and founder of Porcupine Tree, Steven Wilson, and Israeli rock singer Aviv Geffen. Together, they have released three albums under the moniker: Blackfield and Blackfield II as equal partners, and Welcome to my DNA with Geffen taking a more dominant role. A fourth studio album, titled Blackfield IV was released on 26 August 2013, with Wilson taking an even more passive role. After a brief stint of touring in 2014, Wilson stated his intention to leave the band, although Wilson has been shown to be present in sessions for a fifth Blackfield album, tentatively titled Blackfield V.
