The 2013 Bonnaroo Music and Arts Festival in CA offered listeners an enhanced viewing experience over the 4-day festival. An iPhone and Android app by ChirpVision provided music fans with HD audio and video of any one of the three stages, no matter where they were at the festival.
The ChirpVision apps proved especially useful when music fans were greeted with a rainstorm, but could still watch live performances from the "That" tent, which housed the Chirp WiFi Zone.
