While Black Sabbath is a household name, Virginian heavy metal colleague/doom innovator Pentagram’s moniker is still mostly invoked in diehard hesher homesteads. Last Days Here, a stark documentary chronicling founding Pentagram member and frontman Bobby Liebling’s struggles with a post-rock existence and lifelong drug addiction hasn’t yet rebranded Pentagram with the pop-culture/PR gravitas of Sabbath, but the film did kickstart a Pentagram revival, Liebling’s newfound sobriety and a tour that hits Sister (407 Central NW) on Thursday, Feb. 27. Experience the mighty Pentagram alongside Radio Moscow, Kings Destroy and Leeches of Lore. This 21-and-over doom-fest begins at 8pm, and admission is $25. Earplugs come highly recommended; don’t worry, you’ll still be able to hear the children of the night and the sweet music they make.
