It’s hard to believe that people once thought Woodstock 1969 had a stacked lineup. Rock in Rio has well and truly usurped that ancient festival with the best lineup in human memory. This September will see Foo Fighters, Weezer and Tenacious D join forces for a series of shows across South America.

The trifecta will begin their voyage on September 28th in Rio de Janeiro, Brasil as part of this year’s Rock in Rio, where they will perform alongside Red Hot Chili Peppers, Anthrax, Panic! At The Disco and more. They will then play Bogota, Colombia’s El Campin Stadium on October 1st. Then, Foo Fighters and Weezer will bid farewell to Tenacious D and perform at Estadio Nacional in San Jose, Costa Rica.
