During 1977 and 1978, Rundgren attempted to tour with a true quadraphonic sound system, however it proved ultimately unworkable – despite successfully delivering high-quality sound in a concert setting – due to the enormous technical requirements involved. Since most concert arenas of the day were ill-equipped to host large towers of sound equipment in the rear of the halls, the speakers often had to be hung from the ceiling rigging. This installation could take up to two days to complete, meaning that it was necessary to send two separate sound systems, each with its own, complete set-up crew, out on the road, so that they could "leapfrog" and allow Rundgren to play dates on consecutive days, which would have otherwise been impossible. The system featured a then-new technology called "signal analysis", which required white and pink noise to be pumped through the speakers, in order to set the active equalizers so as to minimize feedback and distortion. The pink and white noise analysis had to be performed twice: once with the hall empty, and then again with the audience present, which many concertgoers found annoying. Additionally, Rundgren's insistence on personally overseeing the acoustic set-up of the system left him exhausted and unable to continue, and he pulled the plug on the experiment.
