The Low Anthem, fresh off a multi-set stop at the Bonnaroo festival this weekend, are in New York City to celebrate the release of their Nonesuch debut, Oh My God, Charlie Darwin, with a performance at the Bowery Ballroom tonight. The Observer Music Monthly gives the album four stars, exclaiming, "it soars, the title track especially"; Paste's Josh Jackson calls it "one of my favorite albums this year." The New York Times writes: "[T]he quieter the music gets ... the more its music inhabits its own otherworldly place, where ghosts and angels hover just out of view."

Amadou & Mariam are set to take Chicago's Park West by storm tonight as they begin the first leg of their summer tour. The Chicago Sun-Times says the couple "front a fiery band that provides a kaleidoscope of music filtering rock, blues, reggae and hip-hop through a Malian sensibility. Her vocals are innocent and welcoming; his blues/rock guitar style is commanding and nimble." The Chicago Tribune declares, "If the duo's vocals are a life-affirming sound that transcends language barriers, [Amadou's] guitar is an instrument of mind-altering eloquence." Time Out Chicago says their new album, Welcome to Mali, "sounds as if it was made, variously, in 1970s flare-wearing New York, in a timeless stretch of desert, and at the kind of party you’d most like to be asked to." Catch the duo on NBC's Late Night with Jimmy Fallon this Monday.

Wilco helped mark national Record Store Day this past Saturday with the limited release of their new concert DVD, Ashes of American Flags, through independent music retailers and on nonesuch.com. Fans in Knoxville got to celebrate up-close with Wilco as the band signed copies of the DVD at the local store The Disc Exchange, video coverage of which was posted online by the Knoxville News. Jeff Tweedy spoke with Spin about Wilco's forthcoming studio album, due out in late spring, described as "a mix of pastoral Americana rock (think 2007's Sky Blue Sky) and experimental studio sounds (2002's Yankee Hotel Foxtrot)."

Allen Toussaint's Nonesuch solo debut, The Bright Mississippi, is set for release on Tuesday, April 21. You can catch a glimpse of the songs, songwriters, and guest artists on the album and take a look behind-the-scenes with Toussaint at piano and producer Joe Henry at the boards in a short video on nonesuch.com/media. The Detroit Free Press gives the album four stars. Rolling Stone says it's "pure Toussaint, emotionally and structurally expansive, yet as keenly done as one of Toussaint's perfectly knotted ties." Dusted magazine says, "It’s quite simply one of the best albums we’ll hear in 2009."

After releasing her debut solo album last week, Sara Watkins took to the road for the start of a monthlong tour in support of the new record. She played with Old Crow Medicine Show through the weekend, and tonight, she performs "Long Hot Summer Days" off the new album on NBC's Late Night with Jimmy Fallon with the album's producer, Led Zeppelin bassist John Paul Jones. Look for support to come from Jimmy's house band, The Roots, as well.

Amadou & Mariam's latest album, Welcome to Mali, was recently described by Chicago Sun-Times music critic Jim DeRogatis as "a constant source of sunshine" in a difficult time for much of the world. In a series of video interviews for Nonesuch.com, with concert footage and archival photos featured throughout, the couple shares some of the inspiration behind their new album, with input from album contributor Damon Albarn, and their lifelong commitment to spreading joy through music. To watch all of these videos, along with a live performance of the album track "Sebeke," visit nonesuch.com/media.

Bay Area native Joshua Redman is back on his home turf this week to play a five-night residency—nine shows—at Yoshi's in Oakland, beginning tonight, with bassist Matt Penman, of the SFJAZZ Collective, and drummer Greg Hutchinson, a featured player on Redman's latest Nonesuch release, the double-trio album Compass. Branford Marsalis tells the San Jose Mercury News of the special affinity between Redman and his drummer, calling Hutchinson "the perfect foil for Josh."

Amadou & Mariam are good at what they do, says NPR music critic Robert Christgau in an All Things Considered album review, and "never better than on their brand-new Welcome to Mali." He says the Damon Albarn–produced opening track, "Sabali," is "terrific" and shows that "Amadou and Mariam absorb ideas from anywhere and sound like they're having a ball." Entertainment Weekly says Albarn's "splendidly atmospheric keyboards and production" move the couple "beyond their comfort zone—much as globalist rocker Manu Chao did for the duo's 2005 breakthrough, Dimanche à Bamako." The Chicago Tribune says the new album "is bolder still" than their last, calling Welcome to Mali "an album that throws its arms around the world, and invites everyone to dance. It succeeds joyously." Flaunt says Amadou & Mariam "capture a feeling absent from many releases in the early 2000s: genuineness."

Dan Auerbach "broadens his style" on Keep It Hid, says NPR's Fresh Air, "to include folk, country and even psychedelic elements." Rock critic Ken Tucker says that, while the solo disc offers Auerbach space to change things up from the full-throttle sound of The Black Keys—the album being "all about creating intimacy"—that's not to say Dan has shied away from his blues-rock roots. Even so, Tucker says it's easy "to appreciate the floating, airy atmosphere of Keep It Hid." Rolling Stone's Smoking Section calls the album "unbelievably awesome ... We can’t stop playing it, top to bottom."

In an interview on ABC's World News webcast, Amadou & Mariam discuss having met at Mali's Institute for Young Blind People more than 30 years ago and explain the central role of music in their relationship's success. Also featured on ABC's site is a Pitchfork video review of the duo's new album. "Welcome to Mali is a brilliantly eclectic album," says reviewer Joe Tangari. "They have it all, really ... This is the kind of album that makes you feel more connected to the world you live in." "It’s hard to go wrong with Amadou and Mariam," concurs Dusted magazine. "[They] make great pop music, and their new album gives us more of it." The Boston Herald gives it an A.

Wilco is set to release a new concert DVD, Ashes of American Flags, on Nonesuch, Saturday, April 18, at independent retailers and nonesuch.com nationwide as part of national Record Store Day. The film, shot in high-def and produced and directed by Christoph Green and Fugazi’s Brendan Canty, presents Wilco live in concert during their 2008 tour. Culled from concerts in five quintessentially American venues—Cain’s Ballroom in Tulsa, Tipitina’s in New Orleans, The Mobile Civic Center in Mobile, The Ryman Auditorium in Nashville, and the 9:30 Club in Washington, DC—it captures the energy, poignancy, and musicality of a Wilco concert and tour.
