k, that's a vocal not used very often in trance songs (duh). But ehm, there are two traxx, who use this vocal. The first one is Jon the Dentist vs Olly Jaye's "Imagination". Second, there's its predecessor, also called "Imagination", but I don't know the producer of the track.

Hope this helps

Imagine???
Then it's Ricky Le Roy.
