[2] Sorgir was made two years after Skálmöld's previous album Vögguvísur Yggdrasils.

The album was produced by Einar Vilberg and recorded at the studio Hljóðverk in Reykjavík.

[3] Arnar Eggert Thoroddsen of RÚV wrote that the album stays within its genre conventions but is the band's most varied to date.

[4] Metal.de complimented the fast solos and rhythm structures, and wrote that the best part was the "melodic offensive" of the last two tracks, "Móri" and "Mara".

[5] Metal Hammer's Dom Lawson wrote: "Whether in full-on longboat assault mode on the marauding, mid-paced Lsjósið or exploring more expansive dynamics on closing tour-de-force Mara, the power of the message and the sincerity of the messengers carries every stirring ensemble splurge forward to Valhalla with maximum uplift.
