The sun dipped between the arches of the Golden Gate, and a perfect San Francisco day was capped off by a flawless California sunset. To the right were the rolling Oakland hills, and to the left was the most stunning skyline on the planet. And on a rock right in the middle of it all were 12,000 people bouncing to one filthy bass line.

The Treasure Island Music Festival brought a cultural gem to a place that more closely resembles a ghost town than a Mecca for Bay Area music fans.

The vibe for the show was undeniably positive. K. Flay, a Stanford-educated yet stunningly edgy rapper, woke up the island in one of the day’s first sets in a fiery display of girl power.

Flavor Flav of Public Enemy brought his go-to sermon, “With peace and togetherness we have power,” to a crowd that was ready to love and to fight.

Porter Robinson didn’t say a word for 55 minutes, but left fields of people gasping for more when his turntables spun to a halt. Treasure Island is not the biggest festival in The Bay, but it is surely among the most fun.
