Wow, this one is gold. Jimi Hendrix played the Washington Hilton on Connecticut Ave. NW -- the same one where Hinkley shot Reagan in 1981. That's right, the guitar god himself played to 4,000 fans in the hotel's international ballroom on March 10th, 1968, accompanied by his bandmates, Noel Redding (drums) and Mitch Mitchell (bass). This one might be cooler than the Beatles playing D.C. in 1964, but I don't want to spark a giant musical debate. They're both awesome finds. Check out the photo below of Jimi tearing up the stage.
