Weekend All Things Considered

Weekends on All Things Considered continues its "Why Music Matters" series with Aria Saadi, an actor and musician originally from Iran. Saadi now lives and works in Vancouver, Canada, where he escaped after running afoul of the Iranian government.

Saadi says he remembers well one of his first encounters with Iranian authorities. A self-taught keyboard player, he was performing at what most Americans would call a normal party.

When Carissa Phelps was 12, she dropped out of seventh grade in the small town of Coalinga, Calif. Her homelife was dysfunctional and soon, she ran away.

Her life on the streets took its toll, and before long the unthinkable happened: she was kidnapped by a pimp and forced into prostitution.

There's currently no cure for Parkinson's, a debilitating neurological disease. There's also no blood test that can detect it, meaning early intervention is almost impossible.

But soon there might be a shockingly easy way to screen for Parkinson's disease. It would be as simple as picking up the telephone and saying "ahhh."

"There's some evidence, admittedly weak, that voice disturbances may well be one of the first or early indicator of the disease," mathematician Max Little tells weekends on All Things Considered host Guy Raz.

Deep inside the National Archives in Washington, D.C., old case files tell the stories of hundreds of thousands of hopeful immigrants to the U.S. between 1880 and the end of World War II.

These stories are in the form of original documents and photographs that were often attached to immigrant case files. Many of them are part of a new exhibit at the Archives, called "Attachments."

For University of Minnesota history professor Erika Lee, one of these attachments turned out to be very special.

Earlier this year, classical percussionist Mike Tetreault walked onstage at Symphony Hall in Boston for the audition of a lifetime: The Boston Symphony Orchestra was looking for not just one but two new percussionists.
