Musician Dimitri Manos offers this unique object: a record with six playable . . . well, sides isn't quite the right word.
Each side of the two-sided record has three overlapping circles, each of which has its own track. You can play by placing the record on the turntable with the right hole among the five in the center.
In this video, Mike Dixon gives a demonstration of how it works. Manos's band American Monoxide composed a piece specifically to make use of the record's unique properties. Because the record makes a chirping sound when the needle crosses two overlapping tracks, the composition incorporates that sound.
Content warning: foul language.

Who remembers the 3-sided album from Monty Python: Matching Tie and Handkerchief? It just had two interlaced grooves on one side, so depending on where along the edge you placed the needle you would get one groove or the other. Lots of people got freaked out when they played it and something different came out for the first time.
