Merriweather Post Pavilion

Today, Wolf Trap National Park for the Performing Arts is a mainstay of Washington, D.C.’s cultural life. The park’s large outdoor auditorium and beautiful green space play host to a variety of performers. However, 50 years ago, some politicians questioned whether it was a wise decision for the government to accept the land gift from Catherine Filene Shouse and build the performing arts center.

The American Masters documentary "Jimi Hendrix: Hear My Train A Comin," includes never-before-aired film footage of a live Hendrix performance at the 1968 Miami Pop Festival, as well as a poignant clip of his final performance in Germany in September 1970, just 12 days before his death at age 27.

Unlike the Miami show, rock music archivists have yet to discover any film record of the legendary guitarist's three performances in the Washington, D.C. area in 1967 and 1968, but those shows have become the stuff of local legend.

The Who vs. Led Zeppelin 

It's one of the eternal questions argued by classic rock aficionados — which of these legendary bands rocked the hardest? Perhaps the only people qualified to make that call were those lucky enough to be at Merriweather Post Pavilion in Columbia, Md. on the night of Sunday, May 25, 1969, when Led Zeppelin opened for The Who in one of the most epic double bills in rock history. It was a pairing of hall of fame live acts that would never be seen again on the same stage.
