The earlier days of stereo, for example Beatles Sgt Pepper and Sly and The Familly Stone. Thousands of examples exist. Duran Duran's sound engineers did lots of tricks...listen to "Tiger" on "Seven and the Ragged Tiger"...not great music but the engineers must have had great liberty and fun in the studio. Another good one is Jean Michel Jarre "Oxygene"...
Today engineers are generally much less aggressive at panning the sound (done too aggresively and it becomes distracting). Sadly compression and added distortion seem to be the most popular tools in the studio today.
To get the sound less anchored to the speaker reverb is used and the opposite channel may be either shifted slightly in phase or even fed in reverse polarity (done properly this can make the sound jump out at you).
