Dancer and choreographer Marta Renzi. Typical of her work is "Mountainview," a half-hour dance narrative that premieres this Thursday, August 3 on the PBS program "Alive From Off Center." "Mountainview" is set at the bar of rundown resort run by three generations of the same family. The families loves and jealousies are played out to the sounds of the jukebox, which features the music of Bruce Springsteen, Tammy Wynette and Aretha Franklin. RENZI choreographed the dances and other movements and collaborated with filmmaker John Sayles on the camera work.
