Last 21st October 2011, radio meet cars meet musicians in the garage bellow Maus Habitos, Future Places Festival HQ in Porto, Portugal. Two radio stations, Radio Futura 102.1 MHz and Radio Manobras 91.5MHz provided their frequencies to carry music and chaos into six audio tuned automobiles from the Portuguese xtremetuning.org community. Peter Principle composed a loose composition, grouping cars, musicians on frequency, garage sounds and more musicias. The complex setup worked into two floors of music, performance and radio, where out of sight musicians where channelled into these powerful, personalized, sound system on wheels.

Performance for 2 radio stations, six cars, one composer, and an innumerable number of musicians.
