Mermaid Avenue: The Complete Sessions, a three-CD-plus-DVD set featuring the lyrics of Woody Guthrie set to music by Billy Bragg and Wilco, is out this Saturday, Record Store Day. American Songwriter gives it four-and-a-half stars, calling the project an "amazing and unique collaboration" featuring Guthrie's "mesmerizing wordplay." Rolling Stone gives it four stars. The A.V. Club gives it an A-."Guthrie gained a new generation of listeners when the original Mermaid Avenue became a surprise hit, and the box set," says the A.V. Club, "promises to do the same. But Mermaid Avenue was even more crucial to Bragg and Wilco, producing some of the best (and best-known) songs of the artists’ careers."

Jessica Lea Mayfield launches a spring tour of the United States with a performance at the Rhythm 'N' Blooms festival in Knoxville, Tennessee, this weekend. Mayfield's set will take place Saturday evening at the John Black Studio. From there, the tour heads throughout the South, making stops in Jackson, Shreveport, Dallas, Houston, Austin, Little Rock, Nashville, and Louisville, as well as two festivals in Mayfield's home state of Ohio: at the Nelsonville Music Festival and Appalachian Uprising.

Punch Brothers have launched the second leg of their North American tour. Having kicked things off with a live broadcast performance of A Prairie Home Companion with Garrison Keillor at New York’s Town Hall, the band recorded a show for NPR's Mountain Stage and set out from there for headlining shows in Pittsburgh and Lexington. The Lexington Herald Leader notes the band's "virtuosity and stylistic cunning" and finds them at their "most exciting and inventive" yet. Punch Brothers' upcoming performances include stops in Knoxville, Nashville, Atlanta, Chattanooga, Philadelphia, New York, and Washington, DC, and a set at MerleFest.

Dr. John is the guest on this week's Jamie Cullum show from BBC Radio 2. Dr. John, whom Cullum calls one of his "true musical heroes" and “the coolest guy in the universe,” discusses his life and career and his new album, Locked Down, which the Boston Herald names Album of the Week. "It’s voodoo rock, dense, strange, tangled, beautiful in its darkness," says the Herald. "It also adds wild, welcome new flavors to the gumbo. West African highlife grooves Fela would flip for are everywhere. ’60s Stax soul sneak in during select choruses and bridges. Shaft-style funk drops in for a few druggy intros and outros." The A.V. Club calls it "an inspired collaboration ... at once classic and modern."

The Joshua Redman Trio, featuring bassist Matt Penman, a member with Redman of the band James Farm, and drummer Gregory Hutchinson, kick off a week’s residency at the Village Vanguard in New York City tonight. "Joshua Redman has lately put his tenor and soprano saxophone to work in the context of James Farm, a superarticulate postbop quartet, with strong direction from all four of its members," says the New York Times. "He returns to a more ostensibly hierarchical trio format here ... The results should be sleek and full of silvery digression." James Farm has a four-night run at the Blue Note in Tokyo next month. Redman and Brad Mehldau conclude their own duo tour next week.

The Black Keys, after selling out arenas all throughout the US, Canada, UK, and Europe, announce their long-awaited return to Australia this October. Their new album, El Camino, has already been certified Platinum there. The band made their headlining debut at an unseasonably chilly Coachella festival Friday, helping to "conquer the cold," Reuters reports. MTV says the weather "was no match for the heat of the Black Keys," and the OC Register says their set "was pure bliss." The band joins Anthony Bourdain for some Kansas City BBQ on No Reservations tonight on The Travel Channel.

Amadou & Mariam, whose new album, Folila, was released in the US last week, is the subject of a feature article in the Sunday New York Times. Even with contributions from Santigold, TV on the Radio, Nick Zinner, Jake Shears, Theophilus London, and more, Folila remains very much an Amadou & Mariam album. "[Amadou] Bagayoko’s driving guitar riffs push the music along, giving it shape, and [Mariam] Doumbia’s vocal lines," says the Times, "ride above the complex rhythms, threading the beat with hypnotic melodies." The duo will be coming to North America this summer, including a newly announced Salt Lake City show with Andrew Bird.
