5 years ago, Norwegian metal stars Ulver invited Sunn O))) to improvise together in a night brightened by the lights of the Aurora Borealis. They recorded three “live in improvisation” pieces and listened to them in the morning. Terrestrials is the fruit of this collaboration blending unusually acoustic metal and drone charming sounds. The album will come out in February 2014 on Southern Lord. Listen below to an excerpt of ‘Eternal Return’, the first taste from the album.
