Explorers on the Earthlike planet Wurlitzer 1015 are dumbfounded when they discover an ancient, mysterious monument brooding over its hills. What can it mean? Where can it have come from?

The archaeological dig is still in progress; but there's no doubt that these platter spinning aliens were here long before we were. And where are they now? Only the cryptic message "8 TRAK RULZ" may point the way.
