Down below are great hits performed by Scandinavian artists. The song "Algir" by Wardruna, used in Vikings Series Season 4 (when Odin tells Ragnar's son about their father's death), made me start this playlist. Most hits are familiarly metal songs, however, with the feels of Scandinavian atmosphere
This is off the topic of Norse Mythology, but it's an interesting Swedish Psychedelic Blues-Rock band with an interesting sounding, you can also check. They also manufacture their own instruments and audio equipment.
I'm very interested in the sounds of Rock bands that manufacture their own instruments, basically they're prone to be Irish bands and bands from that region you mentioned. Thank you for your suggestion I'll try it for sure!!
