Armstrong’s American punk ethos has thrived on noisier protest, but his singing here is a simple joy. Jones has been accused of blandness in the past, but here her voice is a thing of whispered beauty. The surprise is that together their voices blend so well; they read the songs with understated craft, often creating beguiling, timeless duets. The duo are supported by backing that is subdued but expressive.
Foreverly may be a worthy tribute to the Everly brothers, but in reality it is much more.
