Face Down is a post-thrash aggro-metal band, with a quite heavy wall-of-sound guitar style and angry, hardcore-ish vocals from Marco Aro. Comparisons to Pantera are valid, as well as fellow Swedes such as Transport League or Mary Beats Jane, though these guys are perhaps a shade heavier. With Aro leaving for The Haunted, it's unclear whether the band is still around or not.
