Is Hidden Histories a micro-FM station, a sound installation, an audio tour, or a local history trail? Perhaps it is none of the above, or perhaps all four. The existence of such a project in some ways exposes the lack of a critical sound-based vocabulary, especially when attempting to portray particular instances of the convergence of oral history and electronic media in their distinctiveness and social context.

On Friday the 14th of March 2008 ten 'street radio' nodes went live in Southampton narrowcasting Hidden Histories -- stories from Southamptons Oral History Archive selected and arranged to correspond with the location of the 10 nodes.
