If you're talking electronic music you will rarely fin anything as innovative as the Art of Noise circa 83-85. They are sounds unlike any other and even now sound fresh and powerful.
Madonna walked up the aisle with Sean Penn with Moments in Love and Beatbox and Close (to the edit) are dance classics.
Listen to a couple of sample tracks on their myspace page:
