"James Moody is the most beloved jazz musician in the world," reedman Paquito D'Rivera says.

These may be strong words, but D'Rivera is far from alone in his appreciation of the tenor saxophonist, who died in 2010. On the bandstand, Moody was universally admired for his musicality, his generosity — he gave away mouthpieces, saxophones and, once, even the coat off his back — and his ability to illuminate any room with his personal warmth.

Grizzly Bear began in 2004 as a bedroom project for Ed Droste. By 2006, Droste had a full band alongside him: Daniel Rossen, Christopher Bear and Chris Taylor. They released Yellow House the same year, but it was 2009's Veckatimest that propelled the group to worldwide fame.

Billed as "all-ages folk and children's music from East Asia," Rabbit Days and Dumplings collects mostly traditional songs from China, Tibet, Taiwan, Japan and Korea. The album is the creation of Elena Moon Park. She's spent six years playing family music with Dan Zanes, who has a fanatically devoted following among the smaller set. For this project, she brought in dozens of other musicians from around New York City.

Contemporary folksinger Tracy Grammer began her journey in music with her partner Dave Carter in 1998. The duo made three albums before Carter died in 2002 — less than a year before this performance was recorded in April 2003. She has also released three Dave Carter and Tracy Grammer albums in the years since his death, one of which came out earlier this year.

This week, Piano Jazz digs deep into the archives with a session featuring James Herbert "Eubie" Blake. He was the last of the known living original ragtime pianists when he appeared on the program in 1980 with host Marian McPartland.

A NASA spacecraft captured the clearest recording yet of what space sounds like inside Earth's radiation belts. Craig Kletzing, a professor of physics and astronomy at the University of Iowa, explains what causes these eerie chirping noises, and what we can learn from them.
