Rhiannon Giddens, whose debut solo album, Tomorrow Is My Turn, was released yesterday on Nonesuch Records to critical acclaim, celebrated the record's release with a performance of the song "Waterboy" on CBS's Late Show with David Letterman last night. "Oh my god," Letterman exclaimed following the performance. "Oh my god, that was unbelievable." Watch for you yourself here. "Tomorrow Is My Turn confirms the arrival of a significant talent whose voice and distinctive approach communicate the simmering emotion at the core of the songs," says the Wall Street Journal. "Thus, she may prove indispensable."

Punch Brothers recently stopped by the CMT studios for a Live @ CMT session, performing what CMT Edge calls a "sparkling" set of four songs off their new album, The Phosphorescent Blues: “Julep,” “Magnet,” “I Blew It Off,” and “Boll Weevil.” You can watch the performances here. The band was featured on NPR's World Cafe yesterday. They spoke with host David Dye, who calls them "some of the very best acoustic musicians anywhere," and performed three songs from the new album: "I Blew It Off," "Magnet" and "Boll Weevil."

Tigran Hamasyan has unveiled an animated video of the song "Kars 2 (Wounds of the Centuries)," off his new album, Mockroot. The video, which premiered on Les Inrocks, was created by his sister, Melanya Hamasyan. You can watch it here. The song was written about the town of Kars, the ancestral home of Hamasyan's maternal grandparents, a place that became part of Turkey in the years that followed the Ottoman genocide of Armenians during the First World War.

Punch Brothers, the Evening Standard noted in a four-star review of their recent London show, "sounded as sharp as they looked." All the rarer then to find the band dressed casually in a new video that goes behind the scenes of the writing of their new album, The Phosphorescent Blues, which you can watch here. The band previews their forthcoming tour as musical guests on A Prairie Home Companion this weekend, guest-hosted by none other than Chris Thile. Following Rolling Stone's recent exclamation that "Punch Brothers are astoundingly skilled, non-show-offy, and pretty much pushing at the vanguard of really great music you need to listen to right now," PopMatters calls their new album "another triumph for the quintet." No Depression calls it "tremendous," explaining: "These are, after all, five of the most dexterous, creative, imaginative musicians working in any area of music today."

You can watch all three performances here. "It's been several years now that Tigran Hamasyan has stood out in the world jazz scene," says Le Figaro, through translation. "For this prodigy, it is not only his technique that is impressive, but the way in which he literally dives into the notes ... whirling his fingers in a breathtaking ballet."

Pianist Tigran Hamasyan has released a video that goes behind the scenes in the recording studio in Meudon, France, where his new album, Mockroot, was recorded in May of last year.

The song "Hero" by Family of the Year, featured on the soundtrack to Richard Linklater's film Boyhood—and heard throughout the telecast of the Golden Globes as the film picked up three awards last Sunday—can now be heard in a new music video as well.

Rhiannon Giddens, who appears and sings in Apple's new holiday commercial, is featured in a new video that goes behind-the-scenes of the commercial, in which a young girl discovers an old Voice-O-Graph recording of her grandmother at a younger age (Giddens) singing the Gershwins' "Love Is Here to Stay," and uses GarageBand to reimagine the song in a modern context. In the new video, Giddens takes viewers inside a vintage Voice-O-Graph booth and reflects on the power of music to bring people together across distances, generational and otherwise. Watch it here.
