Back in the very early days of commercial stereo, RCA put out a series of albums called Stereo Action (IIRC) where they panned the music back and forth across the sound stage - so it sounded like different instruments would be floating in front of you, walking across the stage, etc.
Prior to that, of course, were the records with the sounds of railroad trains chugging along getting close and farther and moving from left to right between the speakers.
There was even a popular classical album from Mercury with Beethoven's worst (but most popular in his lifetime) orchestral composition called Wellington's Victory. You can hear the British and French forces marching in from the left and right sides playing their respective anthems and meeting in the middle in a great battle with sonic fireworks, percussion, cannons, etc.
So what is old is new again.
