Willie Nelson+Alison Krauss and Union Station+Jerry Douglas+Kacey Musgraves

In this intergenerational gathering of country royalty, the 81-year-old philosopher king of troubadours and the high priestess of bluegrass symbolically pass the torch to Kacey Musgraves, the newest initiate to a club whose membership requires multiple Grammys and the life lessons that earned their stripes. Nelson and Family have never appeared alongside Alison Krauss and Union Station, her band for three decades, including dobro master Jerry Douglas. Musgraves, a Dolly Parton devotee, has got a lot of living to do before she inherits that mantle. Times have changed since the red-headed stranger penned “Willingly” in 1961, but telling it like it is hasn’t.
