Summerfest, Milwaukee

Though it's not known as a hotbed for music, Milwaukee has one of the most impressive summertime music festivals on our list. Taking place over two weeks in late June and early July, Summerfest features a nightly headliner (Bruno Mars and Lady Gaga are already slated to take the stage this year) plus a multitude of other acts. More than 800 bands in total take part, and most estimates put the overall number of attendees at just short of 1 million. The festival has taken place in some form for more than 45 years, with the likes of Bob Dylan, Arlo Guthrie, the Doors, the Beach Boys, and Led Zeppelin headlining during Summerfest's earlier years.
