Their combination of varied songs, structures and melodies, several vocal styles, and obscure spiritual lyrics set the band apart from many others in their genre.
Dolorian recorded their first demos in autumn 1997 at Tico-Tico Studios with temporary keyboard player H. Riihinen.
Entitled simply Dolorian, it was a continuation of the black doom sound of their debut, although with much quieter vocals.
In 2006, the band released their third album, Voidwards, which demonstrated a further shift in their sound and included the usage of dark ambient elements.
On the one hand there are long passages of ambient, psychedelic rock, with heavy flange, and clean vocals: on the other hand, there are loud blackened doom metal passages to contrast the atmospheric stylations, with a blend of two harsh vocals (one high and raspy, the other deep and growly), heavy distortion, and blaring synthesizers.
