A Letter of Red is the seventh album from Sabbath Assembly. The album, produced by Randall Dunn who last worked with the band on their debut Restored to One, marks a return to the shortened song form and tight production of their debut, while demonstrating ten years of songwriting prowess and lyrical advancement. The music on A Letter of Red owes more to the galloping hard rock of the 70's than the progressive meanderings of Rites of Passage. Dunn explains: I tried to find the teenage occult heart of each of the musicians and center them in a place of unity around a familiar and yet futuristic sound. I imagined us all in the cosmos with 70's hi fi headphones on riding a great winged beast airbrushed on the side of a chevy van.
