The Finnish melodic death metal band Insomnium has released a new song “Arch Of The Sky”. It is the third single from the upcoming album “Netherworlds”, which will be out on October 16th, 2026 via Century Media Records. “Netherworlds” will be the tenth album of the band. Insomnium have a collaboration song with Amophis – “The Hour Grows”. The new single “Arch Of The Sky” is melodic and has influence from the music of Amorphis and the Finnish folk melodies.  
Ville Friman comments on the band’s website: “‘Arch of the Sky’ introduces a proggier side of the ‘Netherworlds’, featuring time signature changes and Insomnium’s trademark blend of mellow passages and heavier sections. Lyrically, the song is inspired by Sámi mythology, in which celestial hunters pursue a deer across the arch of the sky in perpetual motion. According to the legend, if the deer were ever caught, the world would come to an end as the roof of the sky collapsed.”
The video is directed and produced by Patric Ullaeus, a founder of rEvolver Film Company AB. He combines a traditional animation with the performance of the band.
