How to recreate this lead ?

[gangrena]

Hi, it's my first post, so - Hello!
Can anyone help me to recreate this "airy", gorgeous sounding lead from Depeche Mode's "It's no good"? It is played in the beggining of the song, but it's more hearable from 1:34 to 1:43. I know it will be hard to do it, because it sounds very complicated. I tried many times, but without any satisfying effects.

Here's the link: http://www.youtube.com/watch?v=_-QPvffO1gs

Ps. I strongly recommend this song for synth-crazy people, such as it is a really well-produced and great sounding song, filled with nice, analog synths.

Thx !
