Six musicians illegally break into an apartment and use the space and it's objects to create music, like some kind of sound terrorists. I was introduced to this before it was expounded upon and fleshed out into a full feature called Sound of Noise (which I also highly recommend), and instantly fell in love with it; the creation of music with mundane objects in a dwelling, the group having planned it like a heist, and the general ridiculous fun of the concept.
