Björk, whose new album, Biophilia, was released this week, is the featured guest on PRI's Studio 360. Björk leads host Kurt Andersen through different tracks on the album and the App, which features a separate component for each track on the album. "For the last two decades, Björk has pushed every boundary she could find," says the show. Now, on Biophilia, "Björk’s odes to the mysteries of the universe can be as intoxicating as any love song." Listen to the segment here.

Björk's new album, Biophilia, is out this week. She spoke with NPR's Morning Edition about the new album and its multimedia components, including the App suite also available this week.

The Daily Mirror calls it "a thrilling record ... Even in Björk’s catalogue there’s nothing that’s been as spectacularly unconventional and wholly successful as Biophilia." PopMatters says "she’s breaking new ground few others know is out there to begin with."

Pat Metheny's US tour with bassist Larry Grenadier continues this weekend with sold-out shows in Chicago, Pittsburgh, and Ann Arbor. The Kansas City Star, reviewing last night's show, raves: "The idyllic concept of angels plucking on harps in heaven is overdue for an overhaul. One possible update is the image of Pat Metheny bent over a guitar ... Metheny creates extraordinarily celestial sounds, with last night's show "exceptionally rapturous even by his standards." Metheny discusses his new album, What's It All About, on today's episode of PRI's Here & Now.

Ry Cooder appeared on the latest episode of BBC Radio 2's Mike Harding show to discuss his latest album, Pull Up Some Dust and Sit Down, which Harding describes as "totally brilliant." BoingBoing places the album "in the tradition of the great titles of Woody Guthrie and Haywire Harry McClintlock ... As you'd expect from Cooder, the songs are musically tight and eminently singable and danceable."

Ry Cooder spoke with BBC Radio 4's Today about his new album, Pull Up Some Dust and Sit Down; the interview was broadcast in the US on PRI's The Takeaway. The Philadelphia Inquirer gives the album a perfect four stars, likening it to "the scrappy populism of Woody Guthrie ... set to an incredibly rich melting pot of folk, blues, country, rock, and norteno." The Chicago Sun-Times too calls him "a modern-day Woody Guthrie." Canada's North Shore News says: "Brilliant stuff."
