A Moment With Pulitzer-Winning Composer Caroline Shaw

How do you write something like Partita for 8 Voices, the a cappella vocal piece that is this year's winner of the Pulitzer Prize for music?

"Very late at night," says the composer, Caroline Shaw, speaking with NPR's Scott Simon. "Sometimes it comes from having a sound in your head that you really want to hear, that you've never heard before, and struggling to make that sound happen in any way you can."

Two Decades Later, Some Branch Davidians Still Believe

Twenty years ago, federal agents clashed with David Koresh's Branch Davidian community near Waco, Texas. The standoff ended with a raid and fire that killed some 80 people. It's remembered as one of the darkest chapters in American law enforcement history.

Two decades later, some of the Branch Davidians who survived the raid are still believers, while a new church group has moved onto the land.

The Raid

Officials Seek Answers In Aftermath Of Deadly Plant Explosion

With the house-to-house search over and the living and dead largely accounted for, the town of West, Texas, began the transition from shock and disbelief to communal grieving.

On Friday night, mourners gathered at St. Mary Church of the Assumption to remember the dead. Many of the dead were first responders who were fighting a roaring fire for 30 minutes before the explosion, which was felt 80 miles away in Fort Worth.

Texas Sen. John Cornyn caused a stir when he suggested that there might be many more people missing than thought.

Suspects' Chechen Roots Draw Eyes To Russia

The Boston Marathon bombing suspects are ethnic Chechens with links to the volatile North Caucasus region of Russia. Moscow's reaction to that fact appears to be as complex as the region's turbulent history.

Hundreds Of Years Old, These Songs Tour Like New

Some stories stand the test of time: Shakespeare's plays, the fairy tales of the Brothers Grimm, and the Child ballads.

If you're unfamiliar with them, they're not for children. They're Scottish and English folk songs from the 17th and 18th centuries and earlier. They're named after Francis James Child, the Harvard professor and folklorist who collected them.

An American In Mali, Teaching The Country's Sounds

Numbers are down at the American International School in Bamako, the capital of Mali.

In just over a year, the country has witnessed a rebellion, a military coup and the occupation by Islamist fighters of the desert northern region, recently largely liberated in a counteroffensive by French-led forces. Despite the troubles, the school is open and classes continue.

Teacher Paul Chandler is taking his combined class of 6th- and 7th-graders through their early paces, learning the Malian music they'll be performing at the annual school concert.

MIT Officer Died Protecting His Community, In Job He Loved

The grisly week that began at the Boston Marathon Monday left one police officer dead.

As police closed in on the bombing suspects Thursday night, law enforcement officials say two officers were shot. One, transit police officer Richard Donohue, is in critical condition at Mount Auburn Hospital.

The other, Sean Collier of the MIT campus police, was pronounced dead Thursday night.

MIT says Collier had gone to respond to a report of an altercation on campus Thursday evening. Soon, word came over the police radio that he had been shot.

A 'Tough, Smart, Proud Town' Meets Terror With Determination

People in Boston can speak for themselves. And do. Loudly, bluntly and often with humor that bites.

It's a city that speaks with both its own broad, homebrew, local accent — although no one really pahks thea cah in Havahd Yahd — and dialects from around the world. It is home to some of America's oldest founding families, and fathers, mothers and children who have just arrived from Jamaica, Ireland, Bangladesh and Ghana.

There are people in Boston who dress in pinstripes and tweeds, and tattoos and spiked hair. Sometimes, they are even the same person.

So Hot Right Now: Has Climate Change Created A New Literary Genre?

When Superstorm Sandy hit New York City last fall, the publisher Farrar, Straus and Giroux, like most everything else, totally shut down. It was a week before power returned to FSG, according to Brian Gittis, a senior publicist. When he got back to his office, he began sorting through galleys — advance copies of books. And one of them caught him off guard.

Its cover had an illustration of the Manhattan skyline half-submerged in water.

"It was definitely sort of a Twilight Zone moment," Gittis recalls.
