Using this extensive backlog of material as a basis, Ottesen conceptualized a trilogy of albums based around the same theme.
Retreating to the studio in the basement of his home with an oil barrel, Ottesen recorded a "bare-bones" demo of songs intended for the trilogy.
The albums' title and format, owing to Ottesen's extensive songwriting sessions in 2009, was revealed on 10 February 2010, the day of the first show of the Studio Tour.
On 11 March Ottesen revealed that 12 songs had been recorded in 12 days, completing the first album in the trilogy.

[6] In an interview with Aftenbladet it was revealed that they would be recording the third installment of the trilogy in December 2011, before the tour supporting Volume II.
They brought back the Stavanger Symphony Orchestra, utilizing them as an integral part of the final album of the trilogy.

To further promote the album, Ottesen and Øyvind Storesund, the group's bassist, embarked on a tour of small venues in Europe, performing as an acoustic double act.
[11] In the ten remaining days leading up to the album's release, the band uploaded videos starring Helge Risa, the pump organist, recorded during the preproduction period for the supporting tour.
It was confirmed in radio interviews conducted around the release of the single that Geir Zahl would be performing lead vocals on two self-composed songs on the album.
Beginning on 1 November 2011, the band asked their fans to get involved with the 11-day countdown to the release of the album, Live i Oslo Spektrum, and "Sonny," their stage musical.
They've also held a contest for fans to come up with a poster design to be sold at their merchandise booth during the tour for Vol.
Janove engaged in an interview with a fan site about the future of the band, where he revealed a few details of the album, such as the name of the first single.
