[1][2][citation needed] Cobalt began as a solo project of Phil McSorley, under the name Grimness Enshroud, who released one demo.

[citation needed] Eater of Birds has been described as featuring "70 minute monolith of blasting war metal, massive thrash riffs, drawn-out crescendoes and ritualistic interludes".

[4] Both albums were out of print for years and commanded high prices on webstores such as eBay, but in April 2013 Eater of Birds was reissued by Profound Lore.

The follow-up to Eater of Birds, Gin, further cemented the duo as one of the very best forward thinking, envelope shredding purveyors of black metal that the US has to offer.

McSorley has stated that the band plan on recording a new album following their East Coast tour in May 2013,[7] and that it will be entitled Slow Forever.

[9] On December 16, 2014, Wunder announced via Cobalt's Facebook page that, once again, McSorley was out of the project due to certain personal differences and viewpoints expressed that aren't agreeable to the band.

[citation needed] On June 23, 2015, Cobalt revealed that Wunder was officially in the studio and actively recording Slow Forever, with a tentative release date of early 2016.
