Chicago + Earth, Wind & Fire

Chicago, heroes of the ’70s, hits town: Expect plenty of key changes and golden oldies from its horn-heavy, soul pop-gone-soft rock back catalog, including “If You Leave Me Now” and “Hard to Say I’m Sorry.” Sharing the bill are funk legends Earth, Wind & Fire; though their show isn't the overwhelming spectacle of ’76, EW&F still brings it live with matching outfits and synchronized choreography.
