"Rumble" is an instrumental by American group Link Wray & His Ray Men. Released in the United States on March 31, 1958, as a single (with "The Swag" as a B-side), "Rumble" utilized the techniques of distortion and feedback, then largely unexplored in rock and roll. The single is the only instrumental ever banned from radio in the United States. It is also one of the first tunes to use the power chord, the "major "modus operandi" of the modern rock guitarist".
