N.I.L. ("Nihilism Is Liberation") is an American ambient black/doom metal band formed in 2004 by N. Imperial. Initially, N. Imperial conceived of N.I.L. as a one-off solo project after his departure from black metal outfit Krieg. When the band consolidated into a duo, with the arrival of J. Marcheski in 2006, the project came to fruition with a self-titled release in 2007.

N.I.L. does not appear in corpse paint, and their lyrics focus on solitude and nihilism. Musically, too, they divert from typical features of black metal (such as fast riffs and blast beats), but are instead characterized by bleak and slow, down-tempo, minimalist drones as well as acoustic passages more common in funeral doom.
