Sorry, i don't have a sample, so this will have to be answered by somebody who was there.

Oscar G played this near the end of his set at Space on Friday, and PVD played it at Ultra (except PVD played it with a loop from Doom's Night over it)

It's a hard, acidy electro-house track with a very pretty epic trance-y breakdown. If you were at either party, you probably know the track I'm talking about. I've never heard it before-- anybody have an id for it?

I can't find a setlist for PVD from Ultra yet
