If you wanted to impress someone, which track?

Rebekah Del Rio-Llorando. This is an accapella version of Roy Orbison's Crying sung in Spanish. I don't know anything by this singer except this one song from the Mulholland Drive soundtrack. Probably the most beautiful reverb I have ever heard. This silenced the room at an audio gathering I attended a few years ago.

Good one Mapman. When I sold some speakers a while back that's the song the buyer asked to play to make sure he wanted them.
