Film Forward, a program of the Sundance Institute designed to enhance greater cultural understanding and collaboration, is bringing a couple of free events to West Philly this weekend.

Wynnefield Library (5325 Overbrook Avenue) will host a screening of the recent Academy Award winning documentary Twenty Feet From Stardom on Saturday, beginning at 1 p.m. The film is about people whose voices are familiar to millions of people, but no one knows their names – backup singers behind some of the greatest musical acts of the 21st century. The screening will be followed by a discussion.

On Sunday, April 13, also at 1 p.m., International House Philadelphia presents The Intersection of Film and Music, a workshop produced in partnership with Film Forward. The workshop explores the many roles music can play in the filmmaking process, how music can enhance or ruin a film, and many other questions related to the creative process of integrating music and filmmaking.

The documentary If You Build It will be used as a case study during the workshop. Peter Golub, Director of the Sundance Film Music Program and composer, and producer Christine O’Malley will discuss the film and its music. If You Build It charts the course of a year in the life of one of America’s most innovative classrooms. Go to ihousephilly.org for more information.
