Despite initially announcing his intention to leave the project in 2014, Wilson instead worked again as an equal partner on a fifth album, Blackfield V, which was released on 10 February 2017.

Geffen performed backing vocals on two tracks on Porcupine Tree's In Absentia album, "The Sound of Muzak" and "Prodigal".

[6] Wilson provided lead vocals on all but two songs, and played guitar or piano on every song except "Scars", which had instrumentation provided by Geffen's band "The Mistakes.”[7] Outside of Israel, the band has received constant comparison to Porcupine Tree, Wilson's most popular project.

In response, Wilson has explained: ...Porcupine Tree would never be so focused on the art of a 3 minute pop song, which I believe.

[11] In a 2008 interview, Wilson discussed Blackfield's future at the time, stating, "I think we're going to tentatively start working on some new songs and that's as far as we've got regarding planning.

"[12] In January 2009, to promote his first English-language European release, Geffen went on a small tour of Europe with the Blackfield live band, with Wilson being billed as a special guest.

Their third album, Welcome to my DNA, was released on 28 March 2011[16] and supported by a European and North American tour following a kickoff concert in Israel.

Wilson said of the band's future: ...just to clarify news elsewhere of a new Blackfield album coming this year – please note that this time my involvement will be as a contributor rather than a member.

I will still be mixing the album, and maybe sing on a couple of Aviv’s songs (there will be other guest singers I understand), but with my complete blessing Blackfield is now under his sole curatorship, a process which really began with Welcome to My DNA"[21][23]Wilson later said that it was his own idea for Geffen to take over the project, because he wanted to concentrate on his solo career and Porcupine Tree in 2012 and 2013, while Geffen wanted to do another Blackfield album right away in 2012, and he felt guilty about holding him back.

[27] In a September 2012 interview with Discord Magazine, Wilson reiterated his stance with Blackfield, stating: I won’t say producing [the fourth album], I am only helping [Geffen], a bit of singing, guitar, mixing whatever it takes but I am not going to tour, it'll be too much, I'll kill myself, would just run myself to the ground.

[30] On 25 February 2013, Wilson released his third solo album, The Raven That Refused to Sing, of which some copies contained a compilation sampler disc of music made by artists on the record label Kscope; one track was a new Blackfield song, "Pills", taken from the forthcoming album.

[35][non-primary source needed] On 29 January 2014, Wilson announced his intention to quit the band after the European tour, due to his increasingly tight schedule with his solo career and upcoming projects.

[45][46] After announcing his signing with Warner, on 24 July Blackfield released the first single, “Summer's Gone”, from their upcoming sixth album For the Music,[47] followed by a second track “Under My Skin” on 2 October.

"[48] Influences for the band include Jim Morrison, Radiohead, King Crimson, Genesis, and Pink Floyd.

The songs "Scars," "Cloudy Now," "Glow," "1,000 People," "Epidemic," "End of the World," "Zigota" and "Garden of Sin" had originally been written by Geffen in Hebrew before being translated into English and adapted by Blackfield.

[11] Some musicians have cited them as an influence, such as Dial,[49] while others have expressed admiration for their work including Jordan Rudess,[50] Arne "Lanvall" Stockhammer of Edenbridge,[51] Nick Barrett of Pendragon, Thrawn of Secrets of the Moon,[52] and Dean Marsh of Gandalf's Fist.
