The Flaming Lips
The Flaming Lips have been rocking crowds ever since the 1980s, and throughout their various critically acclaimed albums and Grammy wins/nominations, they have now found their way to Summerfest more than once. This is definitely one of the top (if not the top) ground stage headliner of the year. Don’t just expect them to perform tracks from their 14th album, With a Little Help from My Fwends (2014), expect a number of their hits throughout the decades to keep Milwaukee live. Watch the group perform at Summerfest in 2011 below.
