Beastie Boys @ Terminal 5 in 2008 (more by Elizabeth Weinberg)
Thanks to Anon for pointing out that The Chicago Tribune has revealed Depeche Mode and the Beastie Boys as headliners at this year's Lollapalooza Festival. That would be IN ADDITION TO Jane's Addiction (who the Chicago paper also confirms) and Tool.
The Lollapalooza date fits nicely in to the gap between Depeche Mode's scheduled NYC & Seattle shows.
Beastie Boys are also playing Bonnaroo.
