Led by vocalist Jamie Myers (ex-Hammers of Misfortune), Sabbath Assembly anno 2017 features guitarist Kevin Hufnagel (Gorguts, Dysrhythmia), who has been with the band since 2011; original Sabbath Assembly drummer Dave Nuss; bassist Johnny Deblase, who also played on the band's self-titled album; and the new addition of second guitarist Ron Varod (Kayo Dot, Psalm Zero, Zvi). Rites of Passage marks a moment in which Sabbath Assembly truly "comes of age" as a unique combination of its members, creating progressive metal influenced by Gorguts and Hammers of Misfortune while maintaining a melodic edge true to the roots of the band in the hymnody of the Process Church of the Final Judgment.
Thematically, Rites of Passage is a reflection on the complexity of the transitional stages of life. Ethnographer Arnold van Gennep first defined "rites of passage" in 1960 as birth, childhood, puberty, marriage, parenthood, religious initiation, and funerals. In our current age, when many eschew these specific rites, Sabbath Assembly's newest songs define transitional moments based on experiences in their own lives that have left them feeling truly changed. The songs on Rites of Passage include stories of losing one's religion (rather than initiation), dissolution of a relationship (rather than marriage), and managing the dementia and physical decline of a loved one (as more profound than a funeral rite).
In a time when others in the occult rock genre remain preoccupied with fantasy and dark mysticism, Sabbath Assembly finds the most profound of transformative moments in everyday experience. Rites of Passage presents its listeners with a set of songs that the band hopes will mirror their own experiences of transition, and in some way provide necessary passage.
