Just yesterday, this “pop-up” piano in Williamsbridge Oval Park was being used to make music as part of a citywide program initiated by the nonprofit Sing for Hope. Today, it’s gone. Vanished. Apparently overnight. Caretakers locked it up last night near the tennis courts on the west side of the park at around 6:30 p.m.. Today, it is nowhere to be found.

If you have any information about it’s whereabouts, please contact Michael Lambert of Mosholu Preservation Corporation at mlambert@mpcbronx.org or (718) 324-4461.
