(CNN) -- Occupy Wall Street organizers are planning a Veterans Day rally and concert featuring folksinger Joan Baez in New York City on Friday, as the movement marks its 56th day.
The Foley Square event, dubbed "Honor the Dead, Fight Like Hell for the Living," marks the first time the Occupy Wall Street movement will hold a permitted event in New York, organizers say.
Baez rose to prominence as a folksinger and songwriter in the 1960s, when she was active in protest movements backing peace and human rights.
The Occupy movement started in New York in September as a call to action against unequal wealth distribution. It has spread nationwide and beyond, with major cities continuing with protests despite clashes with the police.
