Trail of Tears formed in Kristiansand, Norway in 1994 under the initial name Natt before adopting their current name in 1997 to reflect changes in lineup and direction. The band played a blend of gothic metal and symphonic black metal built around the contrast of soprano female vocals and male death metal growls, a pairing that defined their early work including debut Disclosure in Red (1998). Over seven studio albums released through 2013's Oscillation via Massacre Records, the band gradually shifted toward a tenor-and-growl dynamic in place of the soprano contrast. Trail of Tears disbanded in 2013 after nearly two decades of activity.
