Kronos Quartet is in London this weekend for what promises to be a whirlwind of events at the Barbican: both its Open Weekend and Ramadan Nights, its annual festival of Muslim music. Kicking things off, Kronos performs tonight with the man who has been called Azerbaijan's greatest singer, Alim Qasimov, and his ensemble, including his daughter, Fergana. The Times (UK) calls the power of their vocals "devastating" and quotes Kronos's David Harrington as placing Alim Qasimov "up there in the top five of all time" among the world's greatest singers.

Edgar Meyer and Chris Thile released their debut duo album on Nonesuch this week, as well as a deluxe version of the recording with a DVD of performance videos and a behind-the-scenes look at their collaborative process. Tonight, in Boulder, Colorado, they launch a month-long tour that will come to a close at Carnegie Hall. Northern Colorado's Longmont Times-Call speaks with Thile about working with his hero and concludes that tonight's audience is in for "a shot at transcendence."

The Black Keys are on the road again, with opener Jessica Lea Mayfield, who contributed harmony vocals on the Attack & Release track "Things Ain't Like They Used to Be" and recorded her own CD with the Keys' Dan Auerbach as producer. The Knoxville News describes last night's show in that city as "All you want in a rock show." The Houston Chronicle previews an upcoming show by calling the band's recordings as "progressively varied, interesting and exciting."

Laurie Anderson brought her Homeland tour to The Egg in Albany, New York, this past Sunday and resumes the extensive tour at the Cullen Theater in Houston on October 10. The Albany Times-Union says the new piece "could well be seen as the provocative, pointedly political epilogue" to her monumental 1983 work United States, as well as "a full-fledged musical concert," with songs of "considerable political bite or incisive, poetic observations," and, in the case of "Mambo & Bling," also "laced with welcome humor."

Dawn Upshaw joins the San Francisco Symphony and conductor Michael Tilson Thomas tonight in an all-Bernstein program for Carnegie Hall's Opening Night Gala. After the program's premiere last week in San Francisco, the San Francisco Chronicle hailed Dawn's performance as "the high point," citing her "fizzy, funny and wonderfully evocative rendition" of the aria "What a Movie" from the opera Trouble in Tahiti. Tonight's performance, also featuring baritone Thomas Hampson, vocalist Christine Ebersole, and cellist Yo-Yo Ma, launches Bernstein: The Best of all Possible Worlds, the Hall's joint celebration, with the New York Philharmonic, of the 90th anniversary of the composer's birth.

Wilco is encouraging everyone who is eligible to vote in this November's all-important US Presidential election to register now and head out to the polls on Tuesday, November 4. For anyone who pledge to do so, the band is offering a free download of a beautiful, live rendition of Bob Dylan's "I Shall Be Released," recorded in concert with Fleet Foxes this summer. Wilco has also signed on to perform this October at the 22nd annual Bridge School benefit concert organized by Neil Young, with whom Wilco will tour this winter.

The John D. and Catherine T. MacArthur Foundation has announced this year's recipients of its annual fellowship, often referred to as the "Genius" grant. Dawn Upshaw was named a Fellow last year. Among this year's recipients are violinist Leila Josefowicz, who performs John Adams's Road Movies on the piece's 2004 Nonesuch recording; Walter Kitundu, Kronos Quartet's instrument builder in residence; writer Alex Ross, who will interview Upshaw at the upcoming New Yorker Festival; and SFJAZZ Collective saxophonist Miguel Zenón, who appears on the group's two Nonesuch albums.

Edgar Meyer and Chris Thile's self-titled debut duo album is due out tomorrow, and their month-long tour of the States in support of the record kicks off Thursday in Boulder, Colorado. New York Times critic Nate Chinen writes that, though "the mandolin ace" and "the accomplished bassist" first came together almost a decade ago as "prodigy with his mentor," the new collection "wisely presents them as equals," featuring "a busy dialogue between bluegrass and classical music, with blinding displays of dexterity as well as stretches of poplike lyricism."

Randy Newman's world tour got under way last week with stops at Carnegie Hall on Friday, Toronto's Convocation Hall on Saturday, and Boston's Symphony Hall on Sunday. Reviewing the Carnegie Hall show, New York magazine says that
Randy "sang about micro and macro American hypocrisy with more sharpness and poignancy than the combined works of Thomas Frank and Maureen Dowd." The Star-Ledger says "the droll raconteur provided more food for thought than a year's worth of media punditry, and he did it with soul." The Toronto Star calls Randy "a graduate cum laude of the master class of mid-1970s American musical poets" and says his latest album, Harps and Angels, "matches the caustic intelligence and musical virtuosity of his classic 1970s albums Sail Away and Good Old Boys." The Boston Globe calls Randy "pop's most incisive, sharp-witted satirist."

John Adams's latest opera, A Flowering Tree, receives its first recording with the Nonesuch release out Tuesday, followed by Hallelujah Junction, a two-CD Adams retrospective and memoirs of the same name. "Adams's sound-world is still expanding," writes The New Statesman. "In this, the composer's seventh decade, his musical fertility still springs anew." Pitchfork gives A Flowering Tree an 8.4, asserting: "There are few living American composers writing works as universal and relevant as John Adams—and that deserves everybody's attention." The Telegraph, in its review of the forthcoming book, declares: "A musician's memoir would probably not be your first choice for light reading, but make an exception for Hallelujah Junction."

Randy Newman's Harps and Angels tour began earlier this week in Peekskill, New York, and continues downstate with two performances in New York City: a free in-store set at the Apple Store in Manhattan's SoHo neighborhood tonight at 7 PM and a concert at Carnegie Hall tomorrow. USA Today describes a track off the new album as "sublime even by Newman standards." The Richmond Times Dispatch gives the album four stars, declaring: "He’s still in a class of his own, and Harps and Angels is the kind of album that longtime fans really get to celebrate every few years ... He’s in great voice, and his songwriting strikes the right Newman mix of sweet/sour/scathing that makes Harps a record that could have landed just behind 1974’s classic Good Old Boys and seemed like a natural progression."
