Gramofon, 1981 by Wojciech Bruszewski
Following up on a previous post about a record player with four needle arms, here is another earlier example by Polish New Media artist Wojciech Bruszewski. There isn’t much to say about this in English, all that is said is:
Record Player with four arms.
The best results: Pablo Casals - plays the cello in a ‘quartet’.
Many thanks to Michał Brzeziński for the heads up
