Nonesuch Records marked Kronos Quartet's 40th anniversary year with two releases this month: the Kronos Explorer Series five-CD box set and a new album, A Thousand Thoughts. As a highlight of its anniversary season, Kronos was in NYC to perform at Carnegie Hall late last month and was the subject of a marathon stream of music and tributes on Q2 Music, the online new-music station from WQXR. The event culminated in a live, performance by Kronos Quartet from The Greene Space at WQXR, which you can watch here.

Conor Oberst performed seven songs from his forthcoming album, Upside Down Mountain, live at the Greene Space in NYC last Wednesday night as part of Gigstock, a mini festival from WNYC's Soundcheck. You can watch Oberst's performance here. "If the songs he played at Gigstock are any indication," says CMJ, "Upside Down Mountain is going to be a hell of a record."

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." 

Natalie Merchant's new self-titled album is due May 6. The video for the song "Giving Up Everything," directed by Dan Winters and featuring the first music to be heard from the album, has premiered on NPR's First Watch. "Rarely is an artist as honest and revealing as Natalie Merchant in her new video and song, 'Giving Up Everything,'" says NPR Music's Bob Boilen. "Watch the video, let it settle in your bones, and watch again." You can do so here.

There are just two weeks to go before the release of Nickel Creek's new album, A Dotted Line, on April 1. The band previously unveiled two tracks from the album, "Destination" and "Love of Mine," and has now revealed a third, "21st of May," which you can hear here. Sean Watkins wrote the song on May 20, 2011, the day before the supposed rapture as predicted and advertised by Bay Area pastor Harold Camping, whose point of view he sings it from.
