From Belphegor’s official website:

“Yeah it’s great to return to Norway and play the Inferno Festival again. We start the rehearsals on Monday. Expect an intense blood-convent and blasting hellfire. Time for the next chapter. We just finished the second rehearsing session for the new album. Currently we’re working on six brachial sound-collages. We will be recording, mixing, and mastering the as of yet untitled album in Sweden this time around.”
