From the IA mothership:
"Sita Sings the Blues is a refreshingly unique animation that has gotten a rise out of people on both sides of the open and shared culture debate. In the film, Paley weaves together the strikingly personal story of her own divorce with the ancient Indian tale of Sita and Rama. Set to the alluring vocals of Annette Hanshaw, the soundtrack has elicited dispute over rights issues."

"The Archive welcomes this piece of art with open virtual arms, hoping to share this bit of culture with as many users as possible, as Paley has intended. You can download the full length film here, get high-resolution stills here, watch the trailer here, and see an interview with Paley regarding the connection between expression and copyright here"
You can find subtitles at the homepage of Sita Sings the Blues.
