"I have a great relationship with Depeche Mode doing their stuff. Their demos are so advanced; they do so much work before you get in the studio. They wouldn't think of presenting me with a song until it has all the lyrics, the middle eight etc. A lot of bands will turn up with a vague idea for a chorus and go, right; we’ll work it out in the studio. By the third album I did with them (2013’s Delta Machine) where we knew each other so well and were really up for challenging each other, we worked really hard. Because Martin [Gore’s] tracks are very well realised it would be quite a battle to push the songs further. You'd have to really get into the detail to work out how you could make it better, rather than just changing it for the sake of it. Every time we tried to push things further I‘d have Dave [Gahan] do a whole new set of vocal takes, and by the final version of the song he would have done 10 sets of takes. Each time his performance would get better and it would be a gradual process of pushing things forward. From a techy production point of view that was always great."
