While Mexican teenagers bold enough to venture outside in a Fall Out Boy T-shirt and eyeliner face the possibility of being beaten to death—on camera—by the country’s so-called anti-emos, American teenagers get Bamboozle, the Meadowlands music festival now in its fourth year. What was once the province of Northeastern city folk getting over hardcore punk and bad relationships in damp basements has become, in this country, big business—an assimilation signaled by the incongruous presence of Snoop Dogg atop the first day of this two-day festival. Otherwise, expect emo stalwarts Jimmy Eat World, Paramore, Coheed and Cambria, Panic at the Disco, et al., plus literally hundreds of their junior peers. What these kids risk is a sunburn and odious rap rock from Gym Class Heroes, but the genre remains some of the best music for and by adolescents ever produced—valued here to the tune of $50 per day, and in Mexico City or elsewhere outside of New Jersey, considerably higher.
