Call it rasper's delight: two gravel-voiced singers share a bill.

On 31 January 2011 the singer shared the official video of the first single from her upcoming full-length studio album ¡Viva!

What's more, the original performances were oratoriolike events, in which the singers, narrator and band shared the stage, almost statically.

But the two singers share a composure, understatement and taste for unusual material.

Both singers share songwriting duties as well as receiving associate producer credit for the album.

Where the two singers share common ground is in their fundamental rhythmic confidence.

Two extraordinary singers disguised as scruffy rock guys share the bill.

On January 10, 2013, the singer shared the third and final preview of the single, prior to its release.

All the singers shared a raw, melismatic, unrestrained delivery.

The singer shares the same acoustic environment and is placed on the same arc as the strings to produce a completely natural effect overall.
