This song is about a girl who evokes tremendous passion in a guy. The title is a play on "Trip Wire," which is a low-placed wire that often sets off a trap. Bono sings about being caught up in all her "wires."
U2 played this for the first time on a RTE Television show called TV Gaga. Promoted as a "different" U2 sound, they played a raw version with no processing. The producer of the show was a friend of the band.
Bono played the harmonica on this track, an instrument he first started playing when the band was just starting out and attempting to cover the Neil Young song "Heart Of Gold
The Joshua Tree was the second U2 album produced by Daniel Lanois and Brian Eno. Lanois plays an electric autoharp called the Omnichord on this track. "It produces this beautiful bell-like sound and in the case of 'Trip Through Your Wires' it sounds like an organ," Lanois told Sound On Sound. "I plugged it into Edge's gear, his echo devices and whole amplification system. If you listen closely to that track you can hear this jangling in the background."
The album was an important milestone in the band's career. Not only does it remain the best-selling release in their catalog, with 25 million copies sold worldwide, but it also brought them their first Grammy Award. In 1988, it took the prize for Album Of The Year among highly esteemed competitors, including Michael Jackson's Bad, Prince's Sign O' The Times, Whitney Houston's Whitney, and the Dolly Parton/Linda Ronstadt/Emmylou Harris collaboration Trio.
This was used in the 1990 movie State Of Grace, starring Sean Penn.
