The vocals were recorded with a Beyerdynamic M88 and an Allen & Heath limiter, which gave him his signature guttural sound. “This limiter probably cost 100 quid or something, and it had one slide kind of knob that let you get either more compression or less compression, and it gave very basic forms of fast attack, slow attack, fast release, slow release,” Padgham says. “Doing the demos at home, Phil realized that if he had the limiter on a very slow attack but fast release, and if he sang a word that began with a sharp consonant like a ‘k’ or ‘t,’ the initial front of the ‘k’ would get through the limiter before it started limiting, so we'd have this very pronounced front to a word that had that kind of consonant. He would sing into this limiter, using it almost as an instrument. Also, there's a vocoder on the words ‘I remember’ in the second verse.”
