Kate McGarrigle passed away last week after fighting a rare form of cancer, clear cell sarcoma. Along with her sister Anna, Kate was responsible for a body of work over 30 plus years that was as striking for the quality of their songwriting as it was for the wholly unique and personal sound of their music and, especially, their intertwining vocals. Here, Nonesuch Executive Vice-President David Bither offers his own remembrance.

Kate McGarrigle, one half of a famed folk music duo with her sister Anna, has died of sarcoma at the age of 63. The sisters' last full-length album was the 2005 Nonesuch release The McGarrigle Christmas Hour, featuring family and friends, including Kate’s children Martha and Rufus Wainwright. Donations in Kate's name are being accepted at the Kate McGarrigle Fund, which raises money and awareness for the fight against sarcoma.

Emmylou Harris and Kate and Anna McGarrigle will be among the artists celebrating the legendary singer-songwriter Pete Seeger, in honor of his 90th birthday, at a special Madison Square Garden concert event, Sunday, May 3. All proceeds will go to the Hudson River Sloop Clearwater, the organization Seeger co-founded in 1966 to fight pollution on New York's longest river. Also on stage will be the honoree himself, along with a diverse line-up of artists, including Bruce Springsteen, Eddie Vedder, Joan Baez, Ani DiFranco, Steve Earle, Ben Harper, Ladysmith Black Mambazo, and many more.

The McGarrigle Christmas Hour brought more than a little holiday cheer and flair to Carnegie Hall's hallowed Stern Auditorium on Wednesday night. It was a family affair, with Kate and Anna McGarrigle, Kate's children Rufus and Martha Wainwright, their aunt Sloan Wainwright, and many other extended family members by marriage, birth, and longtime friendships, including Emmylou Harris, Laurie Anderson, Lou Reed, Justin Bond, and Jimmy Fallon. The New York Times writes: "Although the program still includes the kind of pristine, ancient-sounding French carols performed by the sisters that used to dominate the show, the younger city folk have added a new flavor."

With the holiday season bringing with it so many family traditions, one of the more welcome over the past few years has been The McGarrigle Christmas Hour, a concert at Carnegie Hall inspired by the repertoire of Kate and Anna McGarrigle's 2005 Nonesuch album of the same name. The album is a collection of traditional and contemporary holiday songs and a celebration of family and friends, featuring Emmylou Harris, Anna’s daughter Lilly Lanken, and Kate’s children Martha and Rufus Wainwright, all of whom will perform at tonight's show. Also included among the concert's special guests are Laurie Anderson, Lou Reed, Teddy Thompson, Linda Thompson, Jimmy Fallon, and Justin Bond.
