This song from October is a great example of early-era U2: slightly post-punkish, pure raw power. The Edge's delay is less smooth, more jagged and serrated, and each note comes back like a tireless knife-fighter. "There's a fire inside, when I'm falling over," Bono sings. "There's a fire in me when I call out." And judging by the seething furocity lying in this song, you believe him.
