Sara Watkins kicked off a months-long tour as special guest of Jackson Browne over the weekend. "Cheerful and charming, Watkins was totally at ease," says the Charleston City Paper of Sunday's show. "Watkins also handled the melodies and harmonies with cool authority, and she dazzled with several fiddle solos that demonstrated her virtuosity." Her new album, Sun Midnight Sun, on which Browne makes a guest appearance, is due out on vinyl next Tuesday, July 24, and is available to pre-order in the Nonesuch Store.

Singer/songwriter Fatoumata Diawara’s debut album, Fatou, will be released in North America on August 28, 2012, and is now available to pre-order in the Nonesuch Store. Diawara will tour the US this fall. She has been receiving rave reviews since the album’s release in the UK and Europe last year. The Telegraph says “this stylish debut doesn’t put a foot wrong"; Pitchfork calls it "beguiling." Diawara uses elements of jazz, pop, and funk along with her ancestral Wassoulou tradition in her songwriting. John Paul Jones, Toumani Diabate, and Tony Allen all make guest appearances on Fatou.

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."

Saturday, July 14, 2012, marks what would have been folk legend Woody Guthrie's 100th birthday. Billy Bragg, who, with Wilco, put music to Guthrie's words on the acclaimed Mermaid Avenue albums, has been touring North America with those songs, culminating this weekend with a set at the Woody Guthrie Folk Festival in Guthrie's Oklahoma hometown, multiple events in his adopted hometown of New York City, and a final show in Maryland. Bragg begins his European summer tour later this month.

The Pat Metheny Unity Band—Chris Potter on sax and bass clarinet, Antonio Sanchez on drums, and Ben Williams on bass—takes its month-long European tour to Italy this week. That follows Sunday's show at London's Barbican Hall, to which the Guardian gives four stars, calling the Unity Band "a group of blazing virtuosi with musical intelligence to match." Jazzwise says: "Metheny’s solos remain a thing of wonder: melodic at any tempo and packed with fresh ideas." The European tour continues through July 22; the US tour begins at the Caramoor Festival on July 29.
