I got recorded a really strange atmosphere in Washington this summer. To get the real crazy touch I played the american national anthem in the style of Jimi Hendrix and mixed it with the original sound in a stereo file. You can adjust the sound using your stereo balance. On the left you have just the guitar, on the right just all the rest.
