The Haden Triplets

Separately, Petra, Rachel and Tanya Haden have worked on vastly different musical projects. But when they come together to cover classic country music, the result is a treat and a trip in time.

Joseph Calleja

He's a young tenor with an old-school style and all the world's top opera houses want him. Calleja's expressive shading and dynamic control hearken back to an earlier era — and he's funny.

Diane Cluck

Watching Cluck perform jams the senses. It's almost easier to imagine some tiny spirit in her chest is controlling the action, turning a pitch wheel with one hand and a tone knob with the other.

Lowland Hum

It's hard to convey the sound of two people in love, but Lowland Hum does that effortlessly. The married couple's music is mostly unadorned and pure, with considerable attention to detail.
