 The chorus meets twice a week during school hours to practice, and performs throughout the year at school functions, local events, and on special requests.The PS22 chorus was founded in 2000 by the school's music teacher, Gregg Breinberg, who led his 2001-2002 PS 22 Chorus to live TV in the aftermath of the September 11 attacks.He started blogging in September 2006 about the Chorus, following requests on a Tori Amos fan page, where he had shared some of his videos.
