Combining the powerful catharsis of soul with trap-tinged production, Bishop Briggs’ first EP announces Sarah Grace McLaughlin as a striking new voice. At times (“River,” “Wild Horse”), McLaughlin’s delivery is haunted, almost bluesy; other times (“The Way I Do”), she manages to tap into the towering, bare-all catharsis of an artist like Adele—a range that makes her one of the more unusual new contenders of 2017.
