Singer-songwriter Martha Wainwright was the guest on NPR's World Cafe yesterday. She spoke with host David Dye about the double-disc set Sing Me the Songs: Celebrating the Works of Kate McGarrigle, released earlier this year on Nonesuch Records, which features highlights from three tribute concerts Kate's children, Martha and her brother Rufus Wainwright led with McGarrigle's sister Anna in honor of the late singer and Canadian Songwriters Hall of Fame member after her death from sarcoma. On World Cafe, Wainwright shares stories of her mother and gives intimate, live-in-studio performances of two McGarrigle tunes: "I Am a Diamond" (written by Kate with her sisters Anna and Jane) and "Talk to Me of Mendocino." Listen to the episode at npr.org.

Proceeds from the tribute concerts, held in New York, London, and Toronto, provided seed money for the Kate McGarrigle Foundation—a non-profit organization dedicated to raising money in the fight against sarcoma and also to preserving her legacy through the arts. Net proceeds from the sale of the album Sing Me the Songs also will be donated to the Foundation. The set was produced by Joe Boyd, who curated the concerts, and features performances by Rufus and Martha Wainwright, Anna McGarrigle, Emmylou Harris, Antony, Norah Jones, and Teddy Thompson, among others. To pick up a copy on CD, MP3, and FLAC, head to the Nonesuch Store, where CDs included a download of the complete album at checkout.

The New York concerts were filmed for a feature documentary entitled Sing Me the Songs That Say I Love You: A Concert for Kate McGarrigle, directed by Lian Lunson. Candid interviews with McGarrigle’s family and friends are paired with rousing performances of her music. The film will make its digital premiere through a variety of platforms and storefronts via the Sundance Institute’s Artist Services program on September 17, 2013; portions of DVD sales will also go to the Kate McGarrigle Foundation.
