As our official real style documentarian, Mordechai Rubinstein—AKA Mister Mort—has photographed Deadhead style at Madison Square Garden and on the beaches of Mexico. But nothing compares, he says, to what he found at The Gorge in Washington, where Dead & Company (the Grateful Dead revival band led by Bob Weir and John Mayer) played two nights earlier this month. “I love the outdoor gear, the Keens, the Merrells!” he says. “It was realer than the realest I’ve ever, ever seen.” Go to a Dead & Co. show at a city’s ballpark and you’ll find plenty of kids wearing heady fashion gear, like Engineered Garments, Kapital, and, of course, Online Ceramics. At The Gorge, an amphitheater set high above the picturesque Columbia River, the old heads and young initiates alike took a more utilitarian approach—the whole point of the legendary jam band venue is to camp out before and after the show. “I kept asking people where the lot was, but you were staying in the lot,” Rubinstein says. “Walk a few feet they’re slinging tees, walk a few feet they’re slinging something else, you know what I mean?” So the Grateful Dead’s Pacific Northwest fanbase showed up in their flannels, their hiking sandals, and their fleeciest homemade merch for the occasion. “Because it was camping, maybe that’s because the gear was extra gear-y and extra good,” Rubinstein says.
