After logging several years of experience with sludge metal icons Cavity and doom prognosticators Acid King, among other bands, New York-based vocalist and guitarist Jason Landrian and L.A.-based drummer Rafael Martinez began working in 2001 on a new project that would ultimately become known as Black Cobra. An eponymous EP eventually saw the light of day in 2004, followed by the full-length Bestial in 2006 and mini-album Feather and Stone in 2007, by which time the duo had developed into a vicious, super-distorted heavy metal machine reminiscent of Mastodon and High On Fire. Their latest release 2011's "Invernal" is receiving rave reviews across the metal community and beyond.
