After spending some time apart to work on other projects, Black Mountain eased back into the void between heavy and haunting that they've long occupied for their fourth LP, 2016's "IV". Their crunchy sludge now a potent force for over a decade, the Vancouver quintet join Cheryl Waters for a heady half-hour of tunes from "IV" that bask in acid-soaked riffs, copious guitar solos, and Amber Webber's otherworldly voice. Recorded 04/22/2016 - 4 songs: Mothers of the Sun, Defector, Line Them All Up, Space To Bakersfield
