For this project I was inspired by all of the concerts I\u2019ve gone to that had a strong visual component. I saw the band Bon Iver at the Santa Barbara Bowl about a year ago and the mood was perfectly reflected by the visuals and light show. It was so inspiring because it took the music to the next level and created a spectacle, as opposed to just a band playing on a stage. It was one of the most memorable concerts I\u2019ve ever been to. This got me thinking about visual music when it came time to start this project. I liked the idea of controlling multiple parameters of hardware and software with one MIDI signal.<\/p>\n
