P and I picked up this book, Music Lust by Nic Harcourt, on a recent trip to Borders. Pardon my saying so, but it makes great bathroom reading.
"As music director of KCRW in Santa Monica, CA, and DJ of the influential "Morning Becomes Eclectic" show, Harcourt uncovers the best in new and overlooked music for over half a million listeners every day."
You may also recall a piece in the The New York Times Magazine on June 26 titled "The Star Maker of the Semipopular: How a Los Angeles public-radio DJ became America's arbiter of cool music." The article was pretty cool, too. Enjoy.
