The Pioneer Award was established in 2012 to honor the career of a historic creator of a major body of musical work that has been a major influence on generations of songwriters. “This year, we join musicians and songwriters from around the world in celebrating Woody Guthrie’s 100th birthday,” says SHOF Chairman Jimmy Webb. “One of the great songwriters of all time, we look forward to acknowledging his brilliance with the first-ever Songwriters Hall of Fame Pioneer Award.” Billy Bragg is currently on tour celebrating Guthrie's centenary with music from the acclaimed Mermaid Avenue albums, on which Bragg and Wilco set Guthrie's words to music.

Jeremy Denk marks the release of his new album, Ligeti/Beethoven, with a performance at NYC's (Le) Poisson Rouge tonight. It's a Critics' Pick in Time Out New York and in New York, which calls him "splendid." The New Yorker calls the program "irresistible." WNYC has made it today's Gig Alert. The Washington Post says of Saturday's performance of the program in DC: "Denk has a way of explicating complicated music by playing it so that it seems self-evident and absolutely graspable—a considerable gift." In a new essay for Newsweek, Denk writes of having chosen a career in music over chemistry: "I knew I wouldn’t cure cancer or anything, but I might discover some beautiful way of playing something that no one else had found."

Punch Brothers pick up their US tour again at Appalachian Uprising in Ohio on June 2, one of a number of festival dates ahead in the US and Europe, in addition to their own headline shows.

The San Jose Mercury News calls last night's show "transfixing ... total exquisiteness." All About Jazz says the Trio's new album, Ode, is "rich, lyrical and full of energy ... a non-stop stream of invention." The Montreal Gazette says: "This may well be [Mehldau's] most interesting, absorbing album to date." The Philadelphia Inquirer calls it "transformative." Blurt says it's "some of the trio's most fiery interplay to date. A most welcome return."

Timothy Andres's I Found It by the Sea was featured in the closing-night concert of the Look and Listen Festival in NYC this week, performed with ACME. The piece "draws on a huge range of styles," says the New York Times. "Mr. Andres is a fine pianist, and he wrote himself a dazzling solo line. His quartet writing is equally rich." Andres performs a solo recital at NYC's (Le) Poisson Rouge later this month and makes his London debut at Wigmore Hall June 8. Earlier this year, he spoke with the new-music blog I Care If You Listen about his debut album, Shy and Mighty, and performed his piece At the River. Watch both here.
