"Bass Trap" (instrumental)
"Recorded for 'The Unforgettable Fire' album at Slane Castle. One of the experimental tracks that didn't make the cut, it came via the Eno bag of tricks. In his case, we used a device that allowed you to trap a short musical passage and loop it ad infinitum. This exact idea went on to become the catalyst of an entire music culture called hip hop. Here we simply looped a few bars of Adam's bass, then I played guitar and Daniel Lanois played pedal steel on top." - The Edge, The Unforgettable Fire 2009
