Now this is a bass.
The Octobass is an enormous, three-string instrument that tunes an octave below a standard double bass. It’s so large that the player has to use special keys on its side to change pitches on each string.
The Musical Instrument Museum – which now seems to be the coolest museum ever – lent out their Octobass to Nico Abondolo for a recording session for the soundtrack to the movie The Hunger Games.
As the video description states: “For best results, turn up your subs!”
