It's not as if you've never seen these names in Monterey lineups, but that's not really the point. What is the point is the second-half century of an annual festival that has adapted to the times but never lost its focus-- bringing the best from all styles en masse for a (relatively) affordable price. The Derek Trucks, on the Arena stage on Saturday, is probably the biggest outlier this year.
As far as tickets go, it's $220 for a three-day pass with Arena access, $110 for three days without the Arena and $35 for a one-day Grounds-only ticket. All classes of tickets give festivalgoers access to the myriad panels, exhibitions and conversations that will be going on from Friday to Sunday. Read more about it here.
