One of the beauties of Summerfest is that a music lover can start listening to one unique brand of music, walk 50 steps in another direction and hear a completely different genre or sound. It's even better when the experience can happen without having to move from a single stage, like it did Sunday night at the Briggs & Stratton Big Backyard with Motown-infused crooner Mayer Hawthorne and experimental musician Tune-Yards.
