Natalie Merchant's new, self-titled album was released earlier this week to great critical acclaim. The New York Times describes the album as "a set of dark, brave, thoughtful and serenely startling songs." NPR's All Things Considered says: "This record gives full rein to Natalie Merchant's voice, which is stronger than ever, especially in her magnificent lower register." A USA Today feature finds Merchant "driven by the same sense of empathy that has always motivated her." Refinery29 says the new album marks "the return of one of music’s most illustrious voices."

Nickel Creek celebrated the release of its new album, A Dotted Line, earlier this month with a number of TV and radio performances, including WNYC's Soundcheck, on which the band performed three tracks from the album—"Destination," "21st of May," and "Rest of My Life." You can hear the full show and watch the three song performances here. "Remarkably, while each member's distinctive musical voice comes through, the chemistry between Thile and Sara and Sean Watkins when they play together has never felt stronger," says the show. "While A Dotted Line documents a more mature Nickel Creek than it once was, yet that joyfully rebellious spirit that so many of us fell for still shines through." 

Nickel Creek performed "Destination," off the new album A Dotted Line, on The Tonight Show Starring Jimmy Fallon on NBC last night and gathered for a web-exclusive video to discuss how they wrote their earlier tune "Helena." Watch both videos here. The band performs live on WNYC's Soundcheck today at 2 PM ET. The Los Angeles Times says: "Fresh energy—and fresh ideas—course through A Dotted Line ... They’ve never blended their voices more thrillingly."

Kronos Quartet's new album, A Thousand Thoughts, is due out next Tuesday, April 8. But you don't need to wait till then to hear it: the new album is streaming in full all this week as Q2 Music Album of the Week. "The album would be worth checking out just for the spectacular roster of guest stars the quartet has brought into the studio over the years," says Q2. "But just as impressive as these stellar cameos is the chameleonic playing of the quartet themselves, who manage to blend themselves into musics from Afghanistan, Vietnam and Austin, Texas, even while the core of their sound remains as warm and steady as ever."

Nonesuch Records releases Caetano Veloso’s album Abraçaço in North America next Tuesday, March 25.

KCRW, also streaming the album, calls it Veloso "at his best." You can download two album tracks, "A Bossa Nova É Foda" and "Um Abraçaço," when you pre-order the album in the Nonesuch Store.
