There's a DJ in my hometown named Christian Pronovost who never ceases to amaze me with his music. He happens to own a very good record store called inbeat that has been around for more than the last decade.
There are so many things he's played that were like what you are describing, but I can't remember all of them, I guess it's an integral part of his style. Some people find him annoying, but for real music lovers his sets are always a trip.
It's like one minute you realise you are dancing to something you weren't expecting to hear (the last time I heard him play it was the Sex Pistols) and then blaaaaam! The beat comes back in!
For me the best DJs are the ones who can understand the element of suprise and put a little drama in their mixes.
