Atavist & Nadja
Atavist and Nadja are doom/drone metal bands from the UK and Canada. They have collaborated on two albums. The first, titled 12012291920/1414101, released in 2007 on Invada Records, a UK based record label. Consisting of two near 30 minute pieces of drone and guitar experimentation, it differs from Atavist's usual style of doom metal, and leans more toward the drone sound of Nadja.
