1969. Man lands on the moon. Half a million strong at Woodstock. Sesame Street makes its debut...and Led Zeppelin perform in the gym of the Wheaton Youth Center in front of 50 confused teenagers. Or did they? Filmmaker Jeff Krulik offers his take on an enduring Maryland legend: did Led Zeppelin play this concert on a frigid Monday, January 20, 1969, during the first Presidential Inauguration of Richard Nixon. Led Zeppelin Played Here presents a mid-Atlantic version of what was happening nationwide as the rock concert industry took shape. Featuring interviews with rock writers, musicians, and fans, and several who claim they were witnessing history that night. 'Zeppelin-in-Wheaton is Washington's own rock-and-roll Loch Ness Monster. Could it possibly be real? Yes. No way. Depends whom you ask.' David Montgomery, Washington Post. Runtime: 80 min.
