If you celebrate by drinking, you can order a Purple Haze, Red Headed Groupie, or nonalcoholic Groupie Grind at the bar. Prefer to play out your main-stage fantasies instead? From 4 to 10 p.m., free Jimi Hendrix-style guitar lessons will go down in the main lobby. And since the "Stock" is nothing without music, on Thursday, August 20, legends Crosby, Stills & Nash will rock the Hard Rock Live. Tickets start at $40, much cheaper than a time machine. So grab your chance to experience history at ticketmaster.com.
