Both songs are described as groovy and nineties-sounding, with heavy bass and guitar. The general vibe of The Blackout is Vertigo meets Achtung Baby, with the deep bass possessing a vibe that somewhat recalls Love and Peace or Else. It has a prominent lyric about "when the lights go out" that got the audience jumping, reportedly to Edge's visible delight, and our sources all believe it will be a popular live track.
The Blackout begins with Edge playing a very distorted guitar; this intro has been compared to Zoo Station or Magnificent. There is also a slow interlude that then erupts back into the chorus, somewhat like the "love, lift me up out of these blues" part of Elevation.
The Lights of Home is described as slower and more atmospheric, perhaps a "grower". It has an acoustic slide guitar riff with a memorable chorus that includes the line "hey now, what's your name?", and there is a little bit of chanting at the end. One source describes the drumming in this song as "amazing".
