Global Citizen Festival 2012 with Neil Young and Crazy Horse + Foo Fighters + The Black Keys + Band of Horses + K'Naan

Neil Young and Dave Grohl top a madly stacked free outdoor concert in Central Park, and you're invited…but there's a catch: The festival bill is meant to raise awareness of the Global Poverty Project, an Australian initiative meant to help wipe out extreme poverty, and the only way you can get free tickets for the big show is to earn them through charitable activities. Pricey VIP deals are also available; see globalfestival.com for complete details.
