This innovative company behind the self-guided audio tours debuted in 2003, offering insider’s peeks at Chinatown, the Lower East Side, Times Square, DUMBO, and the Meatpacking District. All of these are great fun and will take you places no tour bus will, but my favorites are the two very authentic Bronx Soundwalks: “Graffiti,” a tour of Hunts Point and the trail of some of the legendary graffiti artists, narrated by BG183 (also known as Sotero Ortiz), founding member of the TATS Cru and Mural Kings of the Bronx; and "Hip Hop," a Bronx River tour narrated by hip-hop DJ the Original Jazzy Jay, which takes you to the birthplace of hip-hop and the haunts of such rap pioneers as Afrika Bambataa and Cool Herc.
