Slow Forever is the fourth studio album by American black metal duo Cobalt, released by Profound Lore Records in 2016. It is a double album and the band's first with vocalist Charlie Fell, who replaced founding member Phil McSorley. The album leans more heavily into blackened sludge metal, similar to acts like Anciients and Tombs.
Slow Forever received "universal acclaim" according to Metacritic.[1] Writing for Pitchfork, Grayson Currin states that "After replacing their lead singer, the reborn metal duo Cobalt make their best-ever record, as accessible as it is aggressive, with magnetic hooks, shout-along mantras, and sparkling riffs."[4]
