Deus Ex Machina is a Singaporean death metal/thrash metal band, and is one of the few extreme metal acts from Southeast Asia that has gained a following in Europe and the United States. They represent a rarity in the Southeast Asian Metal scenes in favouring a more melodic musical approach and concept-based poetic lyrics in contrast to the more aggressive and brutal stylings of the region. They are also a highly internationalized band, with a background of having band members from different parts of the world.
