"4th of July" is the sixth track from U2's 1984 album, The Unforgettable Fire. The song is an instrumental track and has never been performed live, although Adam Clayton did play it as a warm-up during a soundcheck before U2's concert in San Jose on 20 April 2001. It is the only "ambient" track that U2 have ever released, featuring the co-work, the trademark and the style of Brian Eno and Daniel Lanois.
