Kevel is a sludge / post / progressive metal band located in Athens, Greece. Their music cannot be easily categorized in a single sub-genre, as the four-piece create an unconventional yet coherent sonic boulder, extending away from specific “scene” rules and barriers.
On 5/12/2014 their self-financed album "Hz of the Unheard" was officially released.
