Riverfront Park Soundwalk One can experience the artist audio walking tour by starting at River St. in Troy, NY near Psychedelicatessen and having downloaded the free Recho app (that works best on iphones and ipads). It is a geo-locative experience so you must be standing onsite to be able to hear the audio play. Look for AndreaSoundwalks in the Recho App. The above map helps to guide you through the soundwalk. OR you can use the MP3 audio player below that is not geo-locative. You still get the best and full experience by being onsite and following the route described in the title of each audio track. The above map helps to guide you through the soundwalk. The audio player likes to sometimes play the next track automatically, but please wait until you are at the correct sites before you play the next track. Your feedback on the soundwalk is welcomed here.
