SoapBox Karaoke is an interactive installation. The self-contained socially powered Karaoke machine is equipped with a landline telephone and private number. To use the machine, simply press play. Then, choose a track from a CD, and dial up their senator or representative and sing along into the phone. Each track is backed by Muzak from various archives reminiscent of being on hold. You may also choose to practice your script first by singing it into the microphone.
