Back in the Nineties, Pearl Jam famously sued Ticketmaster in an unsuccessful effort to rein in the runaway costs of attending a concert. These days, many are raising the same concerns — like Doc McGhee, Kiss’ longtime manager. In the late 1970s, when he was a young man on the rock scene, top concert tickets cost $10 to $11 (or about $50 to $55 in today’s dollars). Last year, according to Pollstar, the industry trade that monitors touring, the average ticket price had soared to around $132.
