“With a minimum of online searching, fans of virtually any band from arena-filling superstars to cult-worshiped club acts, can find a Web site or electronic mailing list to feed a habit for live CD’s. Bob Dylan or Bruce Springsteen? No problem. Illicit recordings, or bootlegs, of their concerts circulate soon after the last car leaves the parking lot. But a show by the singer-songwriter Dirk Hamilton or the electronica musician Luke Vibert? Also no sweat. In the music world, you’re nobody until somebody loves you enough to want your bootlegs.”
