When musicians over the age of 50 are the star performers, you expect to see many baby boomers cheering them on. Aging rock music stars usually have baby boomer fans. Younger rock stars are more likely to appeal to millennials, the generation born after 1980. But that is not what happened at the Lockn' Music festival, which took place last month in rural Arrington, Virginia. Many Millennials joined Baby Boomers at the four-day event. The Lockn’ Music festival itself seemed like a time capsule with pieces of music from an earlier time. The performers were musicians like Robert Plant (Led Zeppelin), Carlos Santana, and members of the Grateful Dead.

Concert goer Robin Blomquist and other fans remember going to concerts like this back in the 1970s.

I went to college in upstate New York and they played, you could go to a show every night and still make it to class the next day.

But this music also strikes a chord with a new generation of fans, like Jalen Michals Levy. My mother actually she raised me on rock 'n' roll.

Most Millennials were not even alive during the time when these musicians were famous. Young people come to events like this one, joining people who could be their parents or grandparents. Many wear tie-dye tops and denim -- popular clothing from the 1970s. The worldwide web has countless videos of these musicians performing 40 or more years ago. Blogs and Facebook groups connect like-minded music communities. Older fans tell stories of the good old days. They hope to influence a new generation to experience concerts like these, and recapture the activist spirit of the '70s.
