Sara Watkins begins a months-long tour as special guest of Jackson Browne this weekend; she also joins A Prairie Home Companion at LA's Hollywood Bowl for its final show of the season. The LA Times, reviewing a recent Watkins set, says: "Touring in support of her excellent new album," she performed "well-crafted, honest fiddle, guitar and drum music that drew not only on the bluegrass tradition but also hinted at old-time string band tunes, tossed in a touch of Texas swing, a little dose of rock and a certain Watkins family confidence that finds sustenance in adventure."

Bragg begins his European summer tour later this month.

The European tour continues through July 22; the US tour begins at the Caramoor Festival on July 29.
