Here is the link for the parade at the Marine Barracks in Washington DC. Looks like they do a performance every Friday night, starting June.2nd. The parade includes the marine corps band, colour guard, drum & bugle corps as well as the silent drill team and is and hour and a half in length. I also attached a video clip from Utube so you can see what the silent drill team look like - they're pretty slick!!
