Not wanting the project to be a progressive metal supergroup, the two used it as an opportunity to explore their more esoteric tastes in music, including influences from Comus and Scott Walker.
[1][2] Years later, Åkerfeldt received a surprise e-mail from Wilson who had been given a copy of the Opeth album Still Life by a French journalist.
[8] Originally, Dream Theater drummer Mike Portnoy was to be involved, but was excluded because Åkerfeldt and Wilson felt the music would have little room for drums.
[10] In February 2012, it was announced that the collaboration had signed with Roadrunner Records and that their album would be self-titled and released on 24 April.
[12] The guitar work on the album was handled by Åkerfeldt while Wilson concentrated on the keyboards and song arrangement.
[14] Reflecting back on their experience working together, Åkerfeldt and Wilson were largely positive, noting that they never had any artistic struggles over creative control and that each other's contributions were "exactly 50/50".
[25] In an early interview regarding the project, Wilson went so far as to say that the music sounded unlike anything he or Åkerfeldt had done up until that point, including the Opeth album Damnation.
[12] In the press release for the self-titled first album, Åkerfeldt described the music as "a bit frightening, exhausting, profound and rather intense".
