Lyrically and thematically, Castle's music suggests the last days, with singer Elizabeth Blackwell howling about the end being nigh and inviting listeners to their eternal resting place on "Welcome to the Graveyard," the title track off the San Francisco crew's latest long player. Musically, however, the band refrains from wading into the murk, preferring a throwback metal sound best suited to those who are fans of Ronnie James Dio and/or steadily throwing up the devil's horns at concerts. Witness "Flash of the Pentagram," which builds around a relentless riff that races like a vintage Trans Am, or "Traitors Rune," a stampeding cut that calls to mind the likes of Mercyful Fate.

The evening will kick off with a set from promising newcomer RLYR, a Chicago-based trio that includes members of Pelican (Trevor de Brauw), Locrian (Steve Hess) and Bloodiest (Colin DeKuiper) and sports a sound as heavy and doom-laden as this impressive roster suggests. Mos Generator also performs.
