Sweetest Perfection - Depeche Modehttps://www.youtube.com/watch?v=YN-5W41OA0AAlan Wilder describes how the outro came to be in a Q&A on Shunt, the official Recoil website: "The weird stuff at the end came together during the mixing stage (with François Kevorkian). It's the kind of thing you resort to when you haven't really got an ending ;-)"
In 2006, all of Depeche Mode's studio albums were being remastered. Engineer Kevin Paul told Sound On Sound magazine: "'Sweetest Perfection' was completely crazy. It has lots of tape loops, lots of phasing, all sorts of crazy sounds going on. That was really hard to emulate and I had to put my personal spin on it just to get it to work."
