Over the course of three discs, Tautology is, in Dunn’s words, “a representation of life from the teenage years, through middle-age, until the end of life.” The sounds on the album echo Dunn’s own experiences, veering from aggressive metallic riffs to blissful ambient soundscapes. And while there are shared melodies and harmonies through all three records, each one has its own distinct qualities: Tautology I, which represents adolescence, is angsty, aggressive and occasionally depressive; Tautology II is head-noddy and mid-tempo, and represents middle age; while Tautology III, quiet and ambient, represents one’s golden years.
