Looks like Sunn O))) fans won't have to wait six years between proper Sunn O))) albums like they did between 2009's Monoliths & Dimensions and 2015's Kannon. Sunn O))) is in the studio laying down some new music right now with Steve Albini, who has produced bands like Neurosis, Om, and Weedeater in recent years.
You can hear a whopping three notes in 15 seconds below. It's not much to go on, but considering how different Monoliths & Dimensions and Kannon were from one another, I'm definitely excited for whatever comes next!
