Gold Fields (12:40 PM Monday, Honda Bigfoot Stage): You’re going to have to show up early to see Gold Fields on Monday, in fact, they’re one of only two bands this whole weekend that’s playing before 1pm. But checking out this wonderful Australian group is the best way to start your marathon of synth-pop before Chrvches and Twin Shadow come on later in the day. Check out “Ice,” the atmospheric centerpiece to their 2013 debut.
