Today marks the beginning of the Mayor Rahm Emanuel era.

Mayor Daley completed his 22 years in office Friday, leaving City Hall as throngs of onlookers cheered (though, at least one Chicagoan told the former mayor what he really thought). Saturday, Emanuel led a citywide day of service before taking in a soggy concert, featuring Chicago and other local bands, at Grant Park.

He is to be sworn in at 11:15 AM at Millennium Park’s Pritzker Pavilion. You can WATCH or LISTEN to the proceedings.
