U2 - pride in the name of love, 1984

"Slane Castle had some great rooms. When I first went there I had it in mind to record everything in the ballroom, which was this beautiful very tall room with big mirrors, chandeliers and windows overlooking the river. As it turned out, it was just a little too 'splashy' sounding. It was good for tracks that had an openness but not good for tracks that were quick and required punch. So we used what they called the library for most of the sessions. It was just a rectangular room but we could achieve a denser more powerful sound. We had The Edge's amp outside on this balcony; like there is this long balcony going around the castle and we had him out there for a little while. Initially, it was for the purpose of isolation but it turned out to be a good sound."
