So this isn’t exactly late breaking…BUT the little folk singer has lent her voice to a few friends’ albums this year. Dar Williams latest, My Better Self, includes a haunting duet with Ani on Pink Floyd’s “Comfortably Numb.” Cyndi Lauper’s The Body Acoustic (which hits stores November 8) includes an updated version of “Sisters of Avalon” with Ani and Vivian Green. Also, this summer the Indigo Girls released a collection of demos, rare versions and duets entitled Rarities. They included their duet with Ani on Guthrie’s classic “Ramblin’ Round,” which oringinally appeared on the Righteous Babe Records release 'Til We Outnumber 'Em, a tribute to Woody Guthrie.
