Bootleg recordings are a mainstay of the jam band genre, with bands regularly encouraging fans to tape their concerts and trade the resulting recordings amongst themselves. But now, the very band that led the jam band explosion, is angering its fans by cracking down on a website that offered such bootlegs for free download. The Grateful Dead, which exists these days primarily as a business in charge of marketing old product, wants the bootlegs to be available only for online listening, rather than downloading. Already, the international Deadhead community has roared into action, circulating a petition protesting the action and threatening a boycott.
