Vovkulaka is a metal band from Odessa, Ukraine.
The words you will most commonly see on their social media are "Dark Angry Evil Metal" and "Pain never sounded so good".
I don't know that they sound that evil, per se, though I can't deny that they sound angry. Some interesting background information on the band is that drummer Volk also does some paranormal research, and that the band took part in a campaign to pressure the Kremlin into releasing a political pressure. That could indicate that without being evil themselves, the band may nonetheless have some familiarity with evil.
Or they could be evil themselves, but that wasn't the impression that I got.
I hear some industrial overtones in their metal, and although these are not really metal bands, I can imagine fans of Nine Inch Nails and Wolfmother enjoying Vovkulaka. If that sounds like you, check Vovkulaka out.
