The duo experiment with a wide array of musical styles, frequently work on other projects, and rarely perform live under the Solefald name, leading them to describe themselves as "two stubborn goats pretending to be a band.

They were one of the first bands in the black metal genre to incorporate new elements into the style, including a bag pipe passage in one song.

The band incorporated sounds and techniques that had never been heard in black metal before, using hand claps along with choruses in the song "Philosophical Revolt", jazzy clean guitar passages, and shrieked vocals over piano pieces.

Drummer Tarald Lie and ex-Dimmu Borgir member Jens-Petter Sandvik on the bass completed Solefald's live line-up.

Singing in English and French, Nedland brought back his clean vocals, but also introduced a new style, in the form of hollering.

Jakhelln still used his high pitched wails and shrieks and his lower grunting, but he also introduced a style of spoken word singing.

The band stated that they used this quality because of the multi-layered song structures demanding a thinner sound to allow the many facets of the music to shine through.

Another reasoning was that they wanted to use the recording style at the famed Sunlight Studios to achieve the "old school black metal" sound.

Nedland joined progressive black metal band Borknagar as keyboard player and back-up vocalist.

They incorporated a Steinway grand piano, a male choir, authentic Spanish classical acoustic guitar, violin, and saxophone.

Age of Silence released a new three song EP entitled Complications – Trilogy of Intricacy on October 11, 2005 as a lead into their approaching second full-length.

This two-part saga is based on a story written by Jakhelln about a fictional Icelandic skald named Bragi.

[7] In January 2008, a Solefald remix album, entitled The Circular Drain was released through Jakhelln's independent label, Von Jackhelln Inhuman, signed and limited to 1,000 copies.

In addition to these remixes, the CD also contains the entire Jernlov demo, marking the first time it has appeared on a digital medium.

It also marks Solefald's first guitar solo, brought in by the guest guitarist Vangelis Labrakis of the band Mencea.

In a press release it was stated that "The lyrics on 'Norrøn livskunst' are written in a 'høgnorsk' style approaching the Norse — the sound ought to cut like a knife!

"[9] Aside from music, Nedland is a newscaster for TVNorge, and Jakhelln is a writer/poet, with many published writings including a tetralogy of poems entitled Quadra Natura.
