Mention UNIQUE in contemporary Black Metal and you have to include a number of French bands, like Spektr, a mysterious entity with an irregular music output that always manages to surprise me, or Aosoth, who have recently decided to call it quits, but have left behind a potent body of work.
This is a mix of heightened energy and sustained engagement, including some some of my most played songs of this ilk, by two all-time fave bands: DsO and Krallice.
