The Cristal Baschet is not an instrument you hear very often, so if you’ve never seen someone play one, here are two otherworldly cover of the Interstellar and Harry Potter themes performed on the unusual instrument.

From Wikipedia:

The Cristal Baschet is a contemporary musical instrument developed in 1952 by the brothers Bernard and François Baschet. Models of the crystal organs range from 3.5 to 6 octaves and are made of 56 chromatically tuned glass rods. To play it, musicians rub the rods with wet fingertips.

Metal rods are embedded in a heavy plate to form the elements. Each metal rod is accompanied by an attached glass rod. The metal rod’s length, weight and position at the equilibrium point determine the sound’s pitch. The glass rod is gently stroked with a wet finger to produce sound.
