I think I'm a pretty solid producer and engineer, but there is one specific effect I've always had a hard time reproducing... that shimmery, breathy, bordeline-ghostly vocal sound. Greg Kurstin uses it in a lot of the stuff he produces:
Bird and the Bee
Lily Allen (mainly on the hook)
The new Biebs album makes pretty heavy use of it too. And whether you're a Belieber or not, you have to admit it's a pretty cool effect.
Anyways, I'm wondering if any of you have mixing or production tips to get that sound. I think it brings a lot of emotion to the vocal track and I've been hunting for it for a while. Links, plugin suggestions, audio clips, etc. are all greatly appreciated.
