Mayhem has been playing their 1994 debut album De Mysteriis Dom Sathanas in full live quite a bit over the past few years. Should have you missed any of those shows, you can watch the band's full performance of the album at the Black Christmass Festival in Sweden from 2015 above.
The band posted the stream alongside the following message for fans – "Here’s a treat for you while we work on the new album." The band's next album will be their first since 2014's Esoteric Warfare.
