“Peter B. Lane, president and chief executive officer of the Mann Center for the Performing Arts, will leave the semi-outdoor Fairmount Park facility in mid-September after a decade of shoring up the center’s financial stability and revamping its public identity. The announcement, made yesterday by the Mann Center, said Lane will become CEO of Bethel Woods Center for the Arts at the site of the 1969 Woodstock Festival in Upstate New York.”
