Florence & The Machine and The Vaccines will both be performing alongside The Stone Roses in Eastern Spain next July.
The recently reformed Madchester band - who initially only announced two shows at Manchester's Heaton Park - hinted at worldwide plans when first confirming the reunion.
Speaking at the time singer Ian Brown said "Our plan is to shake up the world. We're going to go round the world next year. We're going to start off in our home town, Manchester, and we're going to play two gigs at Heaton Park and then after that we're going to take it round the world."
They were unveiled as the first act playing Benicassim 2012 - and one of the headliners - earlier this month.
Benicassim 2012 takes place July 12-15 2012 - tickets are on sale now.
