Svavar sent them to studio Tóntækni and the recording sessions began in January 1980 and were concluded in February when the band decided to take a break, which was extended until September, when the album was finished.

Thus, Þagað í Hel came out to the streets by December 1980, on limited edition because the vinyl printing was defected and only 500 low quality copies were released.

After the release of Þagað í Hel, Þeyr gained popularity in Iceland thanks to the critic reviews and the band underwent internal changes with the departure of guitarist Jóhannes Helgason and vocalist Elín Reynisdóttir.

The track-listing translates to English as 1) But..., 2)...Except Joe, 3) Rung (or "Phoned"), 4) Brain-Rock, 5) Singed (sheep's head, an Icelandic delicacy), 6) After the Kill, 7) Hell-Dance, and 8) 555.
