Candlemass are a Swedish doom metal band.  Forming in 1984, they are one of the pioneering acts in doom metal, and are considered as originators of the style.  In an area of the world inundated with it's own unique styles of death metal and black metal, Candlemass created their own niche with their own distinctive style and sound, and they helped bring doom metal into the international spotlight.  Though they have been on occasional hiatus throughout their nearly 20 year history, they have been consistently playing live and recording since 2004.  In 2012, they released what is reported to be their final recording, Psalms for the Dead, though they will continue to perform live.  Candlemass will be making an exclusive US performance, their first in many years, at Maryland Deathfest in 2014.
