The latest in NPR's compendium of the year's best music is a list of the Top Ten "New Music" albums, as chosen by WNYC's Nadia Sirota. On it is Alarm Will Sound's Nonesuch debut, a/rhythmia, which offers a diverse repertoire unified by the works' play on conventional notions of rhythm and pulse. "The idea sounds complex," says Sirota, "but the group makes its crystal-clear point joyfully through engaging programming and performances."

Ry Cooder's monthlong tour with Nick Lowe through Japan, New Zealand, and Australia came to a close last night in Perth. The Age, in its review of the Melbourne show, describes Cooder as "the slide-guitar messiah." The Sydney Morning Herald reports from the Sydney set that his "guitar playing was of subtle beauty and effortlessness. Elegance and class all round on stage, actually." Cooder performs next as a guest of The Chieftans at Glasgow's Celtic Connections festival in January.

West Coast, Left Coast, the Los Angeles Philharmonic's festival curated by John Adams, continues tonight with the composer and Kronos Quartet performing California-inspired music at Walt Disney Concert Hall. Adams will lead the Los Angeles Philharmonic New Music Group in performances of Ingram Marshall's Fog Tropes and selections from Frank Zappa's Yellow Shark; Kronos performs Harry Partch's U.S. Highball.

Three Nonesuch albums have made the list of the Best Albums of 2009 from David Dye, host of NPR's World Cafe: Wilco's Wilco (the album) ("a masterpiece that felt both ambitious and lived-in"), Dan Auerbach's Keep It Hid, and Allen Toussaint's The Bright Mississippi. Dye also picks "You and I," Jeff Tweedy's duet with Leslie Feist off Wilco (the album), among his choices of the year's best songs.

Gidon Kremer and Kremerata Baltica's Nonesuch recording of the complete Mozart violin concertos has received the Silver Award at the Record Academy Awards published by Japan's The Record Geijutsu. Australia's ABC Radio National's Breakfast has chosen the recording as Album of the Week, saying, "played true to the style of when they were written, the music sounds fresh and appealing."

BlakRoc, the collaboration between The Black Keys, Damon Dash, and some of the biggest MCs in hip-hop, was released on Friday; NPR marked the event on Morning Edition. The Washington Post describes the Keys' contribution as "a mix of gritty, jazzy and psychedelic beats that ... often resemble those of Wu-Tang Clan." The Wall Street Journal says unlike some earlier efforts to bring rock and hip-hop together, the Keys offer "the credibility needed to attempt such alchemy." The Village Voice says that here, "they actually improve one another." The Observer gives the album four stars.

Bill Frisell performed with his Trio—Kenny Wollesen on drums and Tony Scherr on bass—at the Kennedy Center last month. You can hear the concert online from NPR's JazzSet. In her introduction, host DeeDee Bridgewater describes Frisell as "a superman of contemporary improvisational music and one of the most compelling artists on the scene today."

The Times (UK) has had its say on the best albums of the decade, covering the best in classical, jazz, world music, and pop, and Nonesuch artists are represented in every one: John Adams at No. 1 on the classical list with Doctor Atomic Symphony; Brad Mehldau and Bill Frisell in jazz; Youssou N'Dour, Orchestra Baobab, "Cachaíto" Lopez, and Amadou & Mariam in world; the Malian duo in pop as well, along with Brian Wilson and Wilco.

BlakRoc, the brainchild of The Black Keys and Damon Dash, releases on “Black Friday” (a.k.a. "Blak Friday"), November 27, the day after Thanksgiving, featuring music by The Black Keys with a star-studded line up of MCs including Mos Def, Q-Tip, RZA, Raekwon, Pharoahe Monch, Jim Jones, NOE, Nicole Wray, and Billy Danze. The Seattle Times calls it the "most interesting hip-hop approach" of the year.

When Joshua Redman joined Brad Mehldau for a duo set at London's Wigmore Hall last month, the Guardian said that with "the eloquent saxophonist" Redman, "Mehldau was often able to let his partner's built-in swing release his most whimsical side." The two perform together again for a very festive occasion: the National Christmas Tree Lighting Ceremony in Washington, DC, on December 3, with a PBS broadcast the following night.

Bill Frisell unveiled a new piece with Mike Gibbs and the BBC Symphony Orchestra at the Barbican in London last Friday. The London Jazz Festival performance will be broadcast on BBC Radio 3's Afternoon on 3 today. "Each year, the London Jazz Festival marshals orchestral resources for landmark special events," writes the Financial Times in a five-star review. "This year’s centrepiece was a platform for Bill Frisell." The Guardian gives it four stars, saying "the graceful balance of order and open jamming in Gibbs's orchestral score let most of this unique artist's character glow through."

John Adams's Naive and Sentimental Music will be featured as part of the New York City Ballet's Opening Night Benefit performance at Lincoln Center tonight. The piece serves as score and title to a new work by Peter Martins, the company's ballet master in chief. "New York City Ballet’s opening-night benefit was obviously planned by someone who threw away the Classic Guide to the Boring Gala handbook," says the New York Times. "Put on your finery and go."
