Here's a quick two minute Ableton Live tip for creating an effect I like to call "Deja Delay."  Traditionally, a delay effect comes after the original signal is heard.  Deja Delay is a production technique that lets listeners hear the delay signal before the original.  It's similar in design to a reverse reverb effect, but the result is different thanks to the use of delay instead of reverb.  Check it out and give it a shot in your productions!
