Alison Krauss & Union Station - Lonely Runs Both WaysThe bluegrass star has excelled with songs by her bandmates and some of Nashville’s best composers. Once again, she covers material by her banjo picker Ron Block, her dobro player Jerry Douglas and songwriter Robert Lee Castleman. But the most memorable moments are Krauss’s tender take on Gillian Welch’s “Wouldn’t Be So Bad” and when her guitarist Dan Tyminski (the singing voice of George Clooney in O Brother Where Are Thou?) lends his bittersweet tenor to Woody Guthrie’s “Pastures of Plenty.”
