I've heard about this story for a while, and yes if you really blast the Experimental Jet Set, Trash and No Star album you can hear other music between the songs. Does anybody know the truth about this? from wikipedia..... "The band stated that the album was recorded over the master tape of Sister to save on tape costs. At the time, the statement was widely believed to be a joke, but many fans claim that when the record is turned up to a loud volume, you can hear Sister playing in its entirety underneath the album." It seems it would have to be mastered over the master tape of Sister, not recorded, for this to make any sense.
