It is with great regret that Flaco Jiménez has had to pull out of Ry Cooder and Nick Lowe’s forthcoming European tour on doctor's orders. Due to physical limitations and severe pain caused by herniated discs in his lower back, the Grammy-winning accordionist is unable to travel or perform for the foreseeable future. He is currently undergoing treatment in San Antonio, Texas. The 19-date tour begins on June 11 in Dublin.

Amadou & Mariam, having turned up the heat during their Welcome to Mali tour opener in Chicago on Tuesday, are set to do the same in Toronto tonight and Montreal tomorrow. Toronto's Globe and Mail spoke with Amadou about his life with Mariam and their love of Canada. The National Post describes the duo's live show: "Amadou unleashes sparkling licks on his gold electric guitar, and Mariam wails joyously and busts out infectious seated dance moves. The audience is rapt." Special offer for fans in NYC: enter to win seats surrounding the stage for the couple's Monday night appearance on Late Night with Jimmy Fallon.

Youssou N'Dour kicks off the Muslim Voices: Arts & Ideas festival in a sold-out concert with his Super Étoile band at BAM on Friday night. The following night, Youssou and the band return to BAM for the NY premiere of the documentary Youssou N'Dour: I Bring What I Love and a post-screening performance. The Village Voice describes Youssou's band as "astonishing" and Egypt, the album at the center of the film, as "a masterful expression of personal faith embellished with Cairean strings and, of course, the slippery Wolof beats that underlie N'Dour's complexly ecstatic mbalax sound."

Amadou & Mariam kicked off their North American tour last night at Chicago's Park West, creating music that the Chicago Tribune's Greg Kot describes as "a steaming cauldron of Mali funk ‘n’ roll that the couple stirred, adding ingredients from countless cultures as needed. They knew when to bring it to a boil and when to let it simmer." The crowd was moving from the start, and its fervor only increased, with Amadou & Mariam's "elastic songs stretching further into a zone where the line between dance and trance blurred." The duo's music, Kot concludes, bridges "cultures, sounds and language with a grace rarely seen on a North American stage."

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.

Allen Toussaint's The Bright Mississippi was released to great critical acclaim, followed by an equally lauded residency at New York's Village Vanguard, and a string of performances in Japan. The Wall Street Journal writes that, with the album, Toussaint keeps alive "the tradition of distinctive New Orleans pianists, within which he clearly belongs; and of jazz, which was never far from the surface of his music ...  He simply possesses each tune fully, courtesy of rolling chords, well-placed tremolos, notable restraint and the defining force of his musical presence." Blurt talks to Toussaint about the project and trusting producer Joe Henry's choice of what he calls "these wonderful songs."

Rokia Traoré, whose most recent album, Tchamantché, was released on Nonesuch earlier this year, is the subject of a feature profile in the Sunday Times (UK), in anticipation of her sold-out concert at London’s celebrated Barbican this Friday. The article highlights both her “flourishing reputation” and the launch of her Fondation Passarelle, an organization she founded to help young people develop the skills needed to enter the music business. In August, she performs two free shows in New York that Time Out includes in its preview of the summer's best outdoor concerts. "With her latest disc," says the magazine, "Traoré wraps her beautiful, velvety voice around moody blues and joyous Afrobeats alike. Be prepared to gape at her lovely vocals, and also to get up and shimmy."
