Rokia Traoré's two-week tour of the US comes to a close this weekend with a performance at the Somerville Theatre outside Boston tonight and a return to New York Saturday for show at the Brooklyn Center for the Performing Arts. Rokia is the subject of a feature article in the Boston Globe, which examines her unique blend of traditional and modern sounds and instruments, contending that she has "found a potent muse in the sound of an old electric guitar," the Gretsch, featured prominently on her new album, Tchamantché.

Brad Mehldau will be joined by mezzo-soprano Anne Sofie von Otter at Carnegie Hall tonight for the world premiere of his new work Love Songs. The piece, written for von Otter, is Brad's third Carnegie Hall commission for voice and song; it is set to poems by Sara Teasdale, Philip Larkin, and e. e. cummings, each poet with a different perspective on love. Mehldau and von Otter will perform a number of American popular songs as well. On the first half of the program, pianist Bengt Forsberg will accompany von Otter on works by Sibelius, Hahn, and Schumann, and perform piano works by Ravel and Dukas.

Rokia Traoré returns to New York City for a performance of songs from her latest release, Tchamantché, at Le Poisson Rouge in Greenwich Village. The Chicago Tribune calls this week's performance at Chicago's Old Town School of Music "riveting," one that showed the many facets of the "fascinatingly complex singer ... who embraces but also stretches centuries-old traditions." Throughout, "the incredible Traoré was in command of stage, song and crowd alike."

Rokia Traoré's two-week US tour with music from her latest Nonesuch release, Tchamantché, continues tonight at the Cedar Cultural Center in Minneapolis. That city's Star Tribune describes Traoré's work as "fearless, sophisticated, genre-bending music" and says her "gorgeous vocals ... express the nuances of intimacy and emotion with the refinement of a calligrapher." The Washington Post describes Rokia's voice as "dramatic and entrancing" but concludes, "The album's real allure is its blend of traditional and contemporary elements ..."

Laurie Anderson performs Burning Leaves, a selection of songs and stories from her various solo shows, in Cleveland, Ohio, this Saturday. She is also a featured artist in the new Guggenheim Museum exhibit The Third Mind, on the influence of Asian among American artists. In the House. In the Fire. Stories 1972–2008, a collection of spoken stories and sounds associated with Laurie's performance work, is included in the exhibit, which runs through April 19. In conjunction with the exhibit, Laurie performs two live solo shows, titled Transitory Life: Some Stories, in the museum next month.

Rokia Traoré's recently released album Tchamantché is lauded as the Malian singer/songwriter's "best and most daring work" in a review for NPR's All Things Considered by Banning Eyre. "Traoré's meld of African and rock aesthetics is understated and as comfortable as it is cool," says Eyre. "The world's less-developed societies have produced many singers who seek to balance musical style and cultural perspective, and to address the larger world. Few manage it with the grace and style of Rokia Traoré."

Fred Hersch will perform two shows in San Francisco this weekend: a free solo concert and conversation at the Community Music Center on Friday and a concert at Herbst Theatre with his new Pocket Orchestra Saturday night. He spoke with the San Francisco Chronicle about his recent triumph over a number of life-threatening illnesses and his return to the stage. "Hersch, who plays jazz with uncommon fluency, feeling and invention," says the Chronicle, "has recovered, regaining his strength through intense physical therapy and getting back to the affirming business of making music."

Philip Glass will lead a diverse line-up of artists for the 19th annual Tibet House Benefit Concert tonight at Carnegie Hall, where the concert has been held since 1993.

David Byrne, Wilco, Allen Toussaint, and Toumani Diabaté (sharing the stage with Béla Fleck) will be among the scores of incredible performers at the 2009 Bonnaroo festival. This year's incarnation of the event will be held June 11–14 in Manchester, Tennessee. In other festival news, Coachella, in Indio, California, has also announced its lineup for 2009. The Black Keys are among the headliners for the festival's opening night, April 17, as are such legendary performer/songwriters as Leonard Cohen and Paul McCartney.

Emmylou Harris, Shawn Colvin, Patty Griffin, and Buddy Miller begin a month-long run of their rollicking Three Girls and Their Buddy tour tonight with the first of two consecutive nights at The Birchmere in Alexandria, Virginia. The tour concludes at the end of the month in Boston, where the Boston Globe says the show "brings together four shining talents and close collaborators who straddle the country-folk-pop axis ... on the road en masse to perform as a foursome, four venerated song catalogs in tow."

The Punch Brothers' US tour is winding through the South this week, having stopped at the Alys Robinson Stephens Performing Arts Center in Birmingham on Saturday. The Birmingham News gives the performance four stars, calling Chris Thile "extremely gifted, both as an instrumentalist and a composer," describing the band's music as "a distinctly modern sound that can be dramatic or lighthearted, solemn or joyful, rollicking or dissonant," and praising its "stellar musicianship. Thile and his bandmates can play just about anything and ace it."
