Wolverine is side project of Nergal from Behemoth established in 1999. Music is hard rock strongly influenced by Danzig. Now band's status is unclear but after 8 years of silence it's probably dead and cold.
Their only release is "Million Hells" promo from 2000. At that time Wolverine had 8 songs composed but only 3 were recorded. It's shame they never made full LP.
