Chris Payne, writing over at Billboard:
Fall Out Boy and My Chemical Romance played Warped in ‘04 and after drawing fervent crowds, were signed on for the next year early; by the time June ‘05 rolled around, “Sugar, We’re Goin Down” and “Helena” were MTV staples, improbably climbing the Hot 100. 700,000 kids came out that summer, more than any Warped before or since (for context, last year pulled 300,000). Individual bands regularly sold over $30,000 of merch per day. Bodyguards were needed for the first time. At summer’s end, the tour’s profits hit seven figures. But Warped’s summer-long slog paid another price; across 48 shows in 59 days, musicians and personnel grappled with oversized egos, volatile — if not occasionally hostile — environments, and a sideshow’s worth of distractions far from home, with a massive mainstream audience suddenly watching.
