"El Altar del Holocausto" is a group from Salamanca, Spain that is difficult to classify. Their sound comes from post-metal to Doom Metal with very dense compositions. The symbolism of this group is really intricate, since as they say, all its members have a great influence from the cold Scandinavian forests. In addition, they are presented as extremely Christian monks, with robes that go from head to toe, which creates a very raw mysterious atmosphere on live shows.
