Callisto
There is more than one artist with this name. 1) Callisto is a Finnish experimental metal band (Turku, Finland 2001-present). Trying to fit the post-metal outfit Callisto into one single category hardly does the band justice. Founded in 2001, the sextet play a timeless, downbeat yet melancholic style of music that is rich in nuances, draws from numerous sources and doesn't really have any obvious fellow creatures or points of comparisons.
