The 2009 Bonnaroo Music and Arts Festival was held from June 11 to 14, 2009 at a 700-acre (2.8 km2) farm in Manchester, Tennessee.
Thursday night included heavy rain, lightning, strong winds and hail.
The initial lineup was released on the festival's website at midnight on February 3, 2009.
Bruce Springsteen and the E Street Band performed Saturday.
The previously annual Superjam did not take place, and for the first time in Bonnaroo's eight-year history, not a single member of the Grateful Dead performed at the festival.
