These guys are touring with Sunn O))) in 2017. If you like drone, you'll surely like this. It wavers between being alternately ethereal and in a heavier frenzied metal bent (with lots of lovely feedback and deep washes of bass and guitar), and in both cases fronted by intense female vocals that broadcast a sense of urgency in almost every song. This is worth checking out; here's hoping to see more of them.
Favorite track: do.no.harm.do.no.wrong.Do.No.Harm.Do.No.Wrong.DO.NO.HARM.DO.NO.WRONG.
