The Secret Sisters are Lydia and Laura Rogers, a duo based in Muscle Shoals, Alabama. Their sweet voices and old-time sensibility caught the interest of the legendary T-Bone Burnett, who took them under his wing, produced their record, and started a label purely to release it.
He also brought in a bunch of old Nashville session musicians to play behind them, using instruments and recording methods from the 1950s. The result is an unabashed throwback and a consistent pleasure. There’s a bit of genteel NPR-ishness to it, sure. They’ll probably play it in Starbucks. But whatever — you’ll pry my love of pretty harmonies out of my cold, dead hands. Or ears, rather.
This tune is called “Why, Baby, Why.”
UPDATE: Turns out this song is a cover of a honkey-tonk classic by George Jones. Thanks to janssen for pointing it out in comments. I feel duly chastened.
