Lollapalooza's two South American festivals - Chile, which premiered last year, and Brazil, which launches in 2012 -- announced their lineups on Monday morning: The two festivals will share some but not all acts on their bills. Lollapalooza Chile and Lollapalooza Brazil will both welcome the Foo Fighters, Arctic Monkeys, Skrillex, Calvin Harris, MGMT, TV On The Radio, Bassnectar, Band of Horses, Thievery Corporation, Peaches, Cage the Elephant, Joan Jett & the Blackhearts, Friendly Fires, Foster the People and Tinie Tempah.

The Foo Fighters will play main-stage closing sets  in both Brazil and Chile -- performances that will mark the Foos' first trip ever in Chile as well as their first Brazilian appearance in over a decade.

Festivalgoers in Chile will see Bjork and Avicii, as well as an eclectic collection of bands including progressive rockers Los Jaivas, the socially conscious Juana Fe, punk rock giant BBS Paranoicos, and the Chilean revelation of rockorgánico, Camila Moreno.

Lollapalooza Brazil will host the return of Jane's Addiction and a special blend of iconic indie rockers from every region of the country, including Plebe Rude from Brasília, Wander Wildner from Porto Alegre and Cascadura from Salvador.

 
"The people of Sao Paulo have been very active--twittering me whom they want to see in the 2012 Lolla lineup," Lolla co-founder Perry Farrell, who received the Bill Graham Award at Billboard's Touring Conference  earlier this month -- said in a statement.  "Judging by all the requests, they are going to erupt. We really delivered for them. Now, I want them to show me how you party in Brasil!"

 
Both of these two-day music extravaganzas will take place in an urban setting, with multiple music stages, an electronic tent, amazing local fare, and a Kidzapalooza area for the little rockers.

 
Lollapalooza Chile will return to O'Higgins Park in Santiago on March 31 - April 1, 2012. Discounted two-day passes are on-sale now.

Lollapalooza Brazil will take place at São Paulo's Jockey Club, April 7-8, 2012. Two-day Pre-Sale passes will be available on November 22 at 0h01 am for current e-list subscribers only. Tickets on-sale to the general public on November, 28 at on the official festival website.
