The Grateful Dead subculture has one of the most unique styles in music fandom. And on Sunday, Deadheads from all corners of the country proved it at Madison Square Garden, where Dead & Company kicked off their fall tour. Dead & Co., led by John Mayer and Grateful Dead guitarist Bob Weir, attracts OG Deadheads who have attended countless shows since the 1970s—one guy, who wore a custom Grateful Dead leather vest under his Dead & Co. varsity jacket, said he had attended upwards of 150 Jerry Garcia sets. For them, Sunday night was a reunion of sorts, and they pulled out gear from their collections of bootleg T-shirts and custom jackets. But Dead & Co. also turns out a new generation of fans who have been initiated into the culture (we did just experience the Summer of Grateful Dead, after all). These kids have embraced a different side of the Deadhead DIY world, and rocked up in their rare T-shirts from the likes of WOBF and From The Lot. Naturally, we had to send Mordechai Rubinstein—AKA Mister Mort, expert chronicler of subcultural style–to hang out and snap the most epic tie-dye T-shirts and stealie patches that he could find throughout the day and night.
