Chicago

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.” Oh, and expect fireworks: They're headlining the Hollywood Bowl’s fireworks finale (though LA Phil–produced concerts will continue throughout the month). Five-time Grammy winner Christopher Cross will kick things off.
