Talking Heads, “Swamp.” Speaking in Tongues, 1983.
Byrne sings with two voices intermingled on this track. The one singing the verses is more or less his usual singing voice. The one mixed way down at the beginning and harmonizing along on the chorus, the nasal, deep-pitched voice uttered through a tightly constricted pharynx? It sounds like some ought-to-be-familiar American dialect. Possibly mid-Atlantic seaboard. Almost sounds Southern, but not quite. (Without looking this up) Byrne grew up in Baltimore, n’est-ce pas? Was he applying a Baltimore accent to that monster voice he was making?
