Brazil will hold its two-day concert series at the Jockey Club in Sao Paulo on April 7 and 8, just a week after the second annual Lollapalooza Chile takes place in Santiago.
MGMT, Joan Jett & The Blackhearts and Lollapalooza organizer Perry Farrell and his band Jane's Addiction will join Foo Fighters and Tempah for the Brazilian shows.
TV on The Radio, Calvin Harris, Gogol Bordello and Foster the People are also on the lineup.
Farrell launched Lollapalooza as a travelling music festival in 1991 with inaugural performers including Ice-T and Nine Inch Nails.
He celebrated the 20th anniversary of Lollapalooza earlier this year with an all-star concert in Chicago which featured Cee Lo Green, Eminem, Ellie Goulding and The Drums.
The next Lollapalooza Chicago festival will be held from August 3 to August 5, 2012 at Grant Park.
