n. an unofficial recording of a concert
This term originated with smugglers and thieves who would hide things in the leg of their
boots. It evolved to
mean a pirated version of something. Some liberal bands such as the Grateful Dead, and more recently Phish and Pearl
Jam allow fans to record their concerts, and distibute these recordings freely as long as they are not sold. Fans refer to such recordings as "bootlegs", even though they are legal.
