You don’t need to reinvent the wheel, if you know how to make a really good wheel. The Secret Sisters slot very well into a lineage of old-reliable wheel-makers in the country tradition. As they sing mellifluously and effortlessly on a variety of old standards and classics, their vocals seemingly haunted by a lap-steel player and a honky-tonk piano player, you probably won’t hear anything you’ve not heard before, but like most good things the whole is mysteriously greater than the sum of the parts – and when those perfect harmonies crescendo against your basilar membrane you’ll remember what music is for.
