° As the concept clearly suggests, the technical requirements for a concert of PB_UP are as small as ever thinkable for electronic music. It is actually part of their philosophy to be able to go any place, open their laptops, start their wireless network and play. Venues should be quiet enough for acoustic performance.

°° Other than electricity for the batteries, the only support for a larger venue could be a fifth laptop (MAC OS X with AirPort) connected to the PA's subwoofers, as bass sounds are the only part of the musical spectrum that unplugged laptops cannot render, for plain physical reasons.
