Most bands are lucky if the bassist can hold some cursory high notes to muster live backing vocals. Four members of Seattle’s Fleet Foxes combined voices with such purity and angel sweetness that I almost felt sorry for the fifth, microphone-less guitarist Skyler Skjelset.

When they sang we were transported. Their hirsute scruffiness and echo-drenched country folk suggested they should have been discovered in lost footage of Woodstock but that’s about as modern as the references get.

Frontman Robin Pecknold’s skyscraping tones sang of forests and rivers, meadowlarks and pines, in elemental songs. Ragged Wood appeared to be a love song for two villagers of the Middle Ages. Pecknold seemed hundreds of years old as he crooned the idyllic simplicity of Tiger Mountain Peasant Song.

Occasionally solo, as on a cover of Judee Sill’s Crayon Angels that melted into original ballad Oliver James, he was mesmerising. With three other falsettos swooning around his own, most notably on innocent reverie White Winter Hymnal and rare moment of raw intensity Your Protector, Fleet Foxes touched perfection.
