The dolly zoom, or Vertigo effect, is an 'in-camera' trick used to create a sense of disorientation and panic (the sensation of falling away from oneself). It is achieved by zooming out and tracking in (or vice versa) simultaneously; the speed should be constant for each variable in order to keep the central focus of the frame unchanged.
It is particularly well known for being used in Alfred Hitchcock's 'Vertigo' (which gives the trick its name) and Steven Spielberg's 'Jaws'.
Excellent summation, you may want to put in a line or two explaining how you may use it in your music video. (Or if you do use it later - blog about it and then link back to this entry)
