As noted earlier this week in the Nonesuch Journal, Knoxville’s Big Ears Festival makes its return for what Vice has called “one of the country’s most audacious musical experiments,” and Kronos Quartet, this year’s Artists-in-Residence, are joined on the line-up by their fellow Nonesuch artists Rhiannon Giddens, Sam Amidon, Laurie Anderson, and Tyondai Braxton. In several cases, and in the festival’s spirit of collaboration and innovation, several of these artists also join each other on stage.

Among those Kronos collaborative performances are a concert of reimagined folk songs with Rhiannon Giddens, and Sam Amidon, and a performance with Laurie Anderson of her piece Landfall, which was inspired by her experience of Hurricane Sandy. Both events take place at the Tennessee Theatre on Saturday.

Prior to those shows, Kronos helps open the festival with a performance of Terry Riley’s The Cusp of Magic with pipa virtuoso Wu Man at the Tennessee Theatre tonight, in celebration of the composer’s 80th birthday year. On Sunday, Kronos helps close out the festival in performances with Tanya Tagaq, Bryce Dessner, and Nels Cline.

Sam Amidon and Rhiannon Giddens also perform their own Big Ears sets: Amidon featuring music from his latest Nonesuch release, Lily-O, Saturday night, and Giddens kicking off her tour with music from her solo debut album, Tomorrow Is My Turn, Sunday afternoon, both at the Bijou Theatre.

Finally, Tyondai Braxton performs his piece HIVE at The Standard each day this weekend. HIVE features five musicians atop oval pods designed by Danish architect Uffe Surland Van Tams. The live music combines synths, samples, and acoustic percussion with lighting and visual effects. Premiered in 2013 at the Guggenheim Museum, tonight’s performance is only the second occasion that HIVE has been presented in North America. Additionally, Braxton hosts a DJ set in the early hours of Sunday morning and takes part in a panel on technology’s place in creativity at the Knoxville Museum of Art that afternoon. Braxton makes his Nonesuch debut with the release of HIVE1, which evolved from the piece he performs at Big Ears, on May 12.

John Adams’s new piece Scheherazade.2 received its world premiere with the New York Philharmonic, led by Alan Gilbert, at Lincoln Center’s Avery Fisher Hall last night. Performances continue tonight and Saturday, both preceded by talks with the composer. Violinist Leila Josefowicz, who has been playing Adams’ music for over a decade and for whom the piece was written, describes the piece as “theatre with sound, unlike any other piece written for the violin,” in a New Yorker preview of the premiere. Also on the program are Lyodov’s The Enchanted Lake and Stravinsky’s Petrushka.

Emmylou Harris and Rodney Crowell—capping off a week that saw the announcement of their forthcoming second duets album, The Traveling Kind—join Vince Gill and Cory Chisel for the Celebrity Barn Dance at the Jaeckle Centre in Thompson’s Station, Tennessee, Saturday night. Proceeds from the benefit event support the Jaeckle Centre, which provides rehabilitation and other veterinary care for horses.

Harris and Crowell will play a series of intimate shows in support of the new album starting May 7, just days before its May 12 release. Rolling Stone, which premiered the album’s title track (co-written by Chisel), says: “The Traveling Kind is probably about as deserving of the term ‘Americana’ as it comes, weaving in elements of our entire historical landscape, mixing notes from the mountains with notes of both the cities and plains.”

Punch Brothers continue the second leg of their North American tour out west this weekend, with performances at Roseland Theater in Portland, with support from Gabriel Kahane, tonight and at Harrah’s Tahoe in Stateline, Nevada, on Saturday. The band, whose performance was recently described as “staggeringly tight and clean” by the Boston Globe, is touring in support of their recent record, The Phosphorescent Blues. Tickets to the shows include a download of the album.

Before tonight's Portland concert, the band gives a Kink.fm performance in the Skype Live Studio at 1 PM PT. Tune in to watch it live at skypelivestudio.com.

The San Diego Union-Tribune's George Varga, previewing the band's forthcoming concert in Chris Thile's hometown, describes The Phosphorescent Blues as "likely the finest album he’s made to date with his virtuoso band." Varga goes on to say of the band: "Bluegrass, contemporary classical, alt-rock, folk, pop, Celtic—few bands have such a dazzling command of so many styles, or the ability to fuse elements of each so seamlessly and with such consistent verve and imagination ... The result is an exhilarating aural synthesis that can be buoyant and inviting one moment, dense and challenging the next, but always richly rewarding." Read more at utsandeigo.com.
