On the acclaimed Mermaid Avenue albums, Billy Bragg and Wilco put music to lyrics by folk legend Woody Guthrie for which he had not written music or made recordings. Tweedy and Bragg were "the perfect pair to conclude that Guthrie ... was a prophetic rock-and-roller with a whole lot to say," said the New York Times. On Record Store Day, April 21, Nonesuch will release Mermaid Avenue: The Complete Sessions, which includes the original two volumes of Mermaid Avenue (the second re-mastered); a third volume with 17 previously unreleased recordings from those sessions; the 1999 documentary on the sessions, Man in the Sand; and a 48-page booklet with new liner notes by Nora Guthrie, lyrics, archival photographs, and facsimiles of lyric sheets and sketches by Woody Guthrie. Pre-orders include an exclusive print of Guthrie’s lyric sheet for “Hoodoo Voodoo.”

The new album pairing works by Polish composer Krzysztof Penderecki and the works they inspired by composer/guitarist Jonny Greenwood, due out on March 13, is featured on NPR's All Songs Considered. Producer Robin Hilton exclaims of Greenwood's 48 Responses to Polymporphia: "You hear that, and I think: everything created by a synthesizer is just so irrelevant and boring now. You hear something that real and organic and knowing that it could be performed live with these string instruments, I mean, that's amazing to me." The Guardian's Tom Service spoke with both composers about the project and says of that piece: "48 Responses isn't just a good piece for a composer who is more used to the studio, it is a dazzlingly imaginative, gripping and novel work, full stop."

Randy Newman launches a month-long tour of Europe with a performance at the Sage Gateshead in England tonight, followed by performances in Glasgow, London, Dublin, and throughout Belgium, Germany, Netherlands, Denmark, and Switzerland. Newman tells the Daily Telegraph about touring: "It keeps me sharp. I worried that there is evidence that says people do their best work before they are 30. But I’m as good or better. I haven’t changed a great deal from when I wrote my first song when I was 23.”
