the Lower Manhattan Cultural Council (LMCC) have online a series of Public Art (notice the Capitals there People!) podcasts audio walking tours of sites and works in – you guessed it! – lower Manhattan. The three thematic (thhhh thh!!) mpTHREEs available are presented by Perry Garvin (who works for the LMCC and also has his own blog) and William Smith, complete with NPR-style slow jazz background music (with the occasional AC/DC guitar riff), whose spoken word message is accented as much by the information presented as by the silence and breaths between the thoughts and sentences.
You can download and enjoy the walking tour at your leisure – that’s the beauty of Public Art.
