There are many bands that existed in the pre-internet world that never really did much beyond their bubble. Probably released a record or two and faded into the oblivion. The internet has helped many of these bands breathe a second life.
Black Hole was a band from Italy that existed in the mid to late eighties. They released a slew of demos and in the middle of that came an LP called Land of Mystery. The band caved in 1990 and not much was heard until the reissues came in the 2000s.
Soundwise, Black Hole mixes the Power/Doom Metal stylings of Candlemass with the haunting horror movie style snyth of Goblin. The two elements blend together wonderfully to create something truly haunting and doesn't feel too dated.
